What a beast of a unit. Love the transparency and honesty on this channel. 👌

Not in the market for this but really appreciate the level of detail and information you provide for products like this in your reviews . Keep up the good work.

Thanks for the review! Fingers crossed we get this stateside!

awesome explanation double thumbs up :-) bought one today after watching your video, got a good boxing day deal .

Thanks for the review - love the lego reference! : )

I just purchased this, I’m very excited!!!

Great review Sam, covered all the bases as usual but not likely to change my Versa out as we have two tanks daisy chained and I'd need two units. Love the honest feedback

Man, that tank is looking beautiful

Sold me on this Sam. Can't wait to pick it up from Deer Park next week

Thanks for a good review 👍

Definitely getting one

Nice review . Quality

Always looking forward for a video...parker..😂😂😂👍🏻

Hey Parker! Thanks for your videos- they’ve given so much information that I haven’t found anywhere else. Have you had any experience with the liter meter 4 yet? I am trying to decide between this, the liter meter 4 and the Versas for a single 75G tank AWC setup.

Nice ! Good video

That looks pretty great. I recently picked up an X1pro2T based on your review video, for continuous kalk dosing. Any thoughts on setting up an AWC using two X1-T’s as opposed to this unit? Scheduling each pump individually to turn on and off at the same time, obviously lose the sensing capabilities, but it’s almost 1/2 the cost. Thanks!

Thanks for the review Sam. I wouldn't mind getting one of these, but have it away from the tank, in the garage, so that it keeps the noise levels down. I presume though this would mean that I wouldn't be able to take advantage of the ATO features of it though? Final question would also be which is your weapon of choice still after the review? Still the liter meter?

Awesome review i love your tank and videos. So i don't recall if you said this but you mentioned the manual water change feature, so in the scenario where you need to dilute an issue in a say a 250 US gallon tank and need to quickly change 200 gallons, how long would that take? I would not want to wait 2 days to try to fix the issue. Thanks!

The pro's of it being able to draw water from far away, and the portability of it I think cancel out the negatives of sound. I always like to buy equipment I think could be used in a variety of ways so I can always repurpose what I have. And the quality aspect of Kamoer is always reassuring for me at least.

Great video again, have you ever heard of the AWC reefloat from England? Cool idea, no so easy to understand for some people, but I think a completely different approach on AWC and easy to rebuild if you don't have to left hands 😉 cu gregor

Thanks for the great review - what configuration would you recommend with a similar setup of Remote RO/Mixing Shed and Display Tank - would you put the unit in the shed (less noisy) or tank end (sensors for sump high/low). How do you use the various sensors when there is separation - would you just rely on the accuracy to perform the simultaneous water in/out ? Cheers.

Just wondering whether you determined what the head height was when you had it connected to the RO tubing?? I saw that it was easily able to pump up your 1m rise in the backyard, but what about say 3m vertically? I’m thinking about the feasibility of running tubing from under my tank, into the roof cavity, then say a 10m run through the roof down into the laundry in my case. Obviously after all that, I’d still want a decent enough flow rate. I ask because I don’t see the head height for the x2sr published anywhere. Thanks!

Awesome review. I am tossing up between this and a Neptune DOS as an auto water change system. What are your thoughts/ opinion on the DOS system? I already have a Neptune apex so that part of it isn't a added cost. All reviews that I can find on KZfaq seem very biased and mainly focus on its setup and not its performance.

Just rewatching your video as I’m considering this unit or the smaller X2S. My question is…. After you converted it over to “Johnguest fittings”, did that smaller diameter line throw out the calibration or the volume of water that the X2SR can move? And if you’re going to swap out for JG fittings then would the smaller and cheaper X2R be the better option? Thanks.

This unit looks awesome!!! Looking at my setup I’d figure I would like it in the garage but what about the ato? Can you extend the cabling? From the quick look at the video the connection looks like a headphone jack

Thanks for this review, Parker… Could you post the no-flex tubing sizes you used to replace the green hoses? I’m thinking of doing the same runs for my fish room setup. Greatly appreciate it!

I just put my Maxi Doser back in the cupboard and dragged the Litermeter back out. A really great test/comparison would be around noise (all systems do pretty much the same in theory). Kamoer vs. EcoTech vs GHL Maxi vs. Neptune DOS vs. Litermeter. With continuous AWC does it really matter how often or quickly it happens? But noise matters unless your pump is outside....

Nice review sam. I still prefer the Litermeter 3 though. You don't want to sell 1 of your Litermeter units by any chance? Seriously over not being able to purchase one here in Australia.

Can you share what you used for adapting the tubing to the 1/4” John guest system. Thanks! Also if I can’t do that way can you tell me what size that green tubing is? Thanks! Chris.

Hey Sam, just picked up this water change pump, what barb connector did you use to connect the stock hose to John guest, im planning on doing the same but can’t find the correct fitting. Appreciate the review video too btw

Killer unit! Question for you on saltwater reservoirs: how long is saltwater useable after you mix it? I was reading that magnesium and calcium will precipitate out after mixing so it doesn’t have a long shelf life.

Hi Sam, can this unit be run in conjunction with a separate ATO? Also can it be connected to an apex?

Hi Sam, thanks for the review. To clarify if it senses an overfill situation it actually stops the AWC pump? Not just sound an alarm and keep pumping? I believe this is the case in the X2S.

Hi Sam, Do you know where is a good place to get 1/4 inch John Guest tube in Melbourne in lengths greater than 10 meters. having trouble finding it locally. I'm looking for around 20 meters. Cheers

Can you use the 2 main pumps for a ATO without the 24DC pump? Does the liquid level sensor use the main refill pump or the small pump?

Hey Sam. How long would it take to push 100L you think. I’m think of having it set up and then just “unrolling the tubing” as needed to do an insta warer change on command.

Just ordered one of these. Going to run the john guest tubing like you did. You think would be any issues using 3/8 tube. How did you join the hard pipe to the machine.

Does Kamoa void warranty if you change the tubing as you’ve demonstrated in the video and something goes wrong?

Hey Sam I have just brought this Kamoer and setup its running great 500ml per hour every hour 800litre setup, my question is do I now need to clean the sand ? I used to do it when changing the water. Now its automated do I even need to clean the sand bed?

How do you think this would go moving water a significant height? Wondering if it would get water upstairs.

I know it’s an older video, did you ever have to calibrate it at all? Did you attempt larger water changes at all? I have had this for a few months now that I bought for my 360 gallon total volume system with the intent of doing 4 gallon water changes a day in the middle of the afternoon, I am using the tubing but my length of runs are longer than what came with it so I had to buy more. I’m having an awful time calibrating the flow speeds to get it to do an even 4 gallons in and 4 gallons out simultaneously, did you struggle with getting it to do the correct amount in and out at all? Or have any tips or suggestions on properly calibrating it?

How do you ever leave your home to go on long vacation (holiday)? We left for about 26 days and had our friend (with plenty of instruction) care for our tank. Now the only living things are the 3 clown fish and mushroom corals. Almost 20 years of an established tank decimated by low salinity (1.023 to 1.020 for about 1 week) which is normally kept at 1.025. Our 55 gallon tank is covered with diatoms and we did some 10% water changes, added phosphate media. We use RO water, got salinity back up gradually in same day we got home and 5 days later we got some cerith and turbo snails to eat the diatoms. How do you leave your home and tank? Are there professionals that come and care for your tank while you are gone?

Being that I am into 3D printing, and 3D printers use stepper Motors, one of the recent developments with 3D printers is silent stepper drivers. I wonder if these machines could be upgraded in the future to use silent stepper drivers to bring down the noise level of the machine?

What did Kamoer have to say about the safety and long-term impact on the pumps when you force it down to John Guest tubing?

Hi Sam, thanks for the review! Please can you confirm that this unit can be permanently plumbed to perform SW water changes and RO ATO.

So if you had to set up AWC to only service the dream reef tank, would you stick with your litremeters or get the kamoa?

A bit off topic Sam but my two clownfish are sticking to the upper corner just like yours. I’ve had them for two months, they’re the only fish in the tank, and I’m bummed! Do you have any hope that they will eventually venture out?

I just received mine and I’m having a few issues, the ends of each tube always drain a few inches of water out of the tube after it stops pumping, also how did you connect the RO/DI line to it? I would really like to do this as it seems much more appropriate, do you have links to what you used?

Hi Sam first off great review really enjoyed it . Second i know its a long shot but i have a quick question , i want to mount this unit under the house and run water lines through floor to tank in my bedroom to cut down on noise , I see the float sensors have a headphone plug that plugs into main unit do you know if i could extend these cables with headphone extension cable so i can run main pump unit under the floor and still run float sensors with extension cables . Thanks in advance for any help .

Hi mate, I'm contemplating freeing up my weekends with one of these. If I can find one in the country. What size stem goes into that plastic tubing?

Would love to have one of these babies

Love your videos i have 8 - 4 ft Fresh water tanks with central 6 x 2 sump what system would you recommend for automatic water change i premix my water in 1000ltr tank to suit required ph Cheers

Hi, what do you recommend buying.... The Kamoer x2SR or Spectrapure Litre meter 4? Thank you

Hey Sam how are you mate. I bought this from deer park afew months back. I'm having trouble connecting the device to my home WiFi? Is that a common issue with these? Cheers

Hi Mate, I’m in Australia and trying to find that exact adapter, are you able to point me out. I’ve also been touch and go about this 2nd version so answered my questions.

Could I accomplish the same with 2 Pro T pumps? Assume it's all within ten feet - no long runs.

Can you do a video on how you converted to John Guest fitting please

Can you please tell me what size tubing I will need? I need like 30 feet of tubing!

I am late to the scene...but still Let me start off by thanking you for the super informative unbiased content you put out for everyone in this hobby. Just like everyone else i also follow yr channel. Thanks again and 👌🏻👌🏻. So now coming to this AWC thing, its really is one of the most sought after things these days and its proving its worth i suppose. I did watch your Litermeter AWC content and this one now. My doubt/question is if the system has a gravity ATO system like in Cade (which even u you have ) how does this AWC work? Does it mean that we have to bypass the gravity ATO system completely and use the sensor based system or is there any other way ? Reason for asking is in next couple of months i am setting up a Cade S21500 and this question is lurking on for quiet some time which will also decide if i shud opt for any of these AWC systems. Thanks and Regards.

When can we get a update on your dream reef tank dude.I am a big fan of your dream reef tank.

hows the noise iwth doing say 40ml / min? atm using versa's for auto water change and happy with them, can barely hear them

Great video. Is it me or is reefing equipment becoming ridiculously expensive?

Did you ever change the hose over to 1/4 instead of the thick hose that came with the pump? I’m thinking about getting a unit to pump from my basement. However I don’t think my wife will appreciate me drilling that big of a hole in the hardwood floor.

Saturday 12:00 Watches Sam's review of the Kamoer X2SR Saturday 13:00 Tries to work out how I could possibly plumb one of these into my house / tank Saturday 13:30 Gives up trying to work it out based on where my tank is / lack of space / lack of clear path to outside water storage & drain Saturday 14:00 Starts manual 10% water change - Approx 30 litres Saturday 14:15 Finished cleaning up the 15 litres of saltwater I managed to dump all over the floor when I accidentally pulled siphon out of the sump during said water change Saturday 14:30 Re-visiting how to add Auto water change to avoid this fiasco again. Options include drilling holes in walls / removing walls / moving house... Whatever it takes! I don't believe in fate, but.....

How do those hydraulic pulsations affect the fish?

I wonder how well this would deal with long hose runs and different water heights.

Would be nice to have this but unfortunately kamoer units aren't available by us anymore, even the ato which you reviewed isn't available as much. Apparently to import its gone 3x the price pre covid so now it's not worth it for the shops

I need to figure out an automatic water changing system for a freshwater aquarium. I need something to green one or two gallons a day down into a sewer and then fill from a safe tap source [well water] .

How often do you need to calibrate the pumps?

All of that extra vibration in the smaller quarter inch tubing would make me nervous about anyting unplugging itself over time

Hi Sam, is this unit available with Dave, deer park Aquariam???

What's the vertical pump ability?

Litremetre still your no.1 for awc?

I was just thinking about getting this, good review!!! , it still as loud if not louder than my Neptune DOS though, I’m looking for a auto water change system that is virtually silent, I was thinking maybe 2 kamoer fx-stp since they are supposedly dead silent

Kamoer x2sr or 2 ecotech versa? Thx

The Ecotech Versa maxes out at 300ml/min

Is that a major bloom in the sand? The "skip the ugly stage" really seems like a myth.

Wow for under 700 bucks this kills the auto aqua which I paid over 400 bucks for, with the wifi control and added sensors which I would want for fresh salt and RO water storage means there would be now worries with running out of saltwater for water change and I could get a warning for low level of top off water etc. The auto aqua has none of that and also just uses basic 12 volt dc pumps for moving water. Definitely a nice system to look at especially for that added peace of mind.

I don’t understand why you don’t use an Apex. You have all these individual components when it can all be in one place. The apex DOS is the best water changer by far.

I'm really sorry but this review is inaccurate. This pump set at 60 rpm will move 110ml in 30 seconds and you can barely hear it. The only reason to have it set to its default speed would be for large manual changes and even then you could set it lower than the default for sure. So it is not loud at all in my opinion. NDOS is 20 times louder and moves far far less water. As for the size and weight it is necessary. The weight actually keeps it grounded and it has zero vibration. When you refer to a product that accurately moves large volumes of water like this indeed does you want it to be heavy. I think of quality when referring to weight in this situation. I ordered 3/8 id black vinyl tubing and it holds the water even in that large of tubing. It runs from DT area to bathroom drain, also to my new saltwater in garage, so even with large tubing and different size run lengths it still changes the exact amount on both heads. This product is worth its weight in gold and should not be compared to any of the water change systems mentioned in this review. Its quality deserves a professional video. I would have edited the back shed footage because I was distracted by the tree growing in. Parker I have watched, enjoyed , and learned from most of your videos. So I would never make it personal. You seem like a great guy so my apologies if any offense is taken but even if the consumers are rushing you to get content out there it is important to not rush it. Personally I don't like loud devices so that part of the review almost made me not make the purchase. Due to the limited availability of all WC systems I went ahead when I found one finally on aqua cave. I am so glad I did and I think if you spend more time with it you will agree it is second to no other WC system on the market at this time. Honestly if there were other videos on this specific product I wouldn't even comment but because this is 1 of 3 out there I feel it would help some get a better idea of how this product works. It is early in my testing but so far this product could change the game on top of the water it changes. I currently have it set up in my home and can't hear it at all. The NDOS in my GARAGE could be heard each and every time it turned on INSIDE MY HOUSE. The X2SR is 3 feet from my DT if that and I can't hear it at all. Zero!! Even when I'm watching it I only hear a soft hum. That is the absolute truth. Go out and get you one of these bad boys, you won't regret it.
