Great video! Thanks for sharing. Great info here.

BRS has become addictive viewing. Great job. I would buy from you if I lived in usa

Great video. Topping off directly from RO here. SOOO much better. Not more buckets.

i built my ATO Res into my sump. The dividing wall is an inch lower than the top of the sump. This way the water in the system is contained no mater what happens. its worked well over the last 4 years on my 90 gallon tank.

been running a saltwater tank for over 10 years now and never used an electronic ATO or carried a single barrel of RO water to the tank. i think its mind blowing the amount of money these electronic ATO's are and from what iv heard there as unreliable as they are expensive. and in case your wondering how i do it just keep reading, in the kitchen under the sink where my RODI unit is i have a 25ltr barrel with a bulkhead fitting at the bottom out of that iv ran 25 feet of RO pipe round to my tank where in the sump a cheap float value is attached. total cost was less the £15, then its as simple as filling the barrel under the sink once a week. its worked flawlessly now for over 10 years nothing has failed or ever let me down, and it blows my mind that people speed silly money to achieve the same result that cost me pennies and now 10 years on its now feeding 2 large tanks and a salt water mixing bin, its fully automated with no electronic moving parts self flushing and self filling with a 6 month quick routine maintenance and TDS check all for less then £75 all these electronic ATO are just over complicating a simple problem and shame on BRS i think you guy should know better ......... and for a 1000 thumbs up i will do a full how-to-guild on how to do a really cheap and reliable top off system that i promise will never fail! something BRS just seems unable todo with out selling you something over priced and just over complex for the job.

Since starting out I've gravity fed RO to the sump which passes through a 12V solenoid valve on a plug timer set to come on 6 times a day for slightly more than the amount of time required to cover the daily evaporation & a float valve at the end of the tubing. In 15 years I've not had any problems touch wood.

Merci pour cette vidéo !!! 👍👍👍

when using a float switch you could have the top off water flow over the float switch to rinse off with RO water.

The Tunze Osmolator Pump is originally a caravan water pump and can be replaced by them. They are cheaper than the Tunze Version. They can get rusty very fast because of the Ro/Di Water which sucks up Ions like Crazy. The "Caravan Version" of the pump is around 10$ and as i already said, its the same.

I love my ato I evap about 50 gallons a week in my 480gal system I got it tied directly to my plumbing and every 2 weeks I check my float switches every other week...

I have made a diy ato for my 24gallon. It has a peristaltic pump controlled by 2 float switches in series. so a low and a high if the low one doesn't activate when the water is back at the correct level the high one will shut it off. Also the resivior is only 2 gallons and would not over fill the tank if there was a total fail. That lasts a 1.5 to 2 weeks. 1 plus being a peristaltic pump it won't back syphon if the pipe fell in the tank. Also that gets around the pump running dry as it just spins and I can use kalkwasser without risking the pump getting damaged. The 1 drawback I can see is if the pipe splits and dumps it on the floor. That would be an issue on all types of ato that use pipes to top up though.

Love these videos!!

Awesome great job guys!

I top off from my 135 gal RODI tank. NS pmup pumps 50' away and two stories up with no problem. I needed a remote power controller EN832 in the basement to turn on the pmup. I have three ATKs and one backup ATK. One old style pmup has ran for two years and one went out in one year. One new style pmup has ran for 2 years and one went out in 9 months. Of six optical sensors I’ve had two go out in two years. I have no FMM failures. ATK doesn’t work well for a hang on the back setup although I have rigged it up to do it on a sump less Frag tank. Wish the magnet was stronger so I add an additional magnet on three pmups a in the RODI tank and one on each sump.

i love my hose reel modified with python hose. it costs more than $80 though. It is 80 for the reel and then another 50 for the python. but still though. it makes water changes so easy.

One thing I noticed is that all the pumps I saw were impeller based. I opted for a peristaltic pump on my ATO and I don’t regret it for a minute.

i have used the smart ato since 2014 and never misses a beat.

I set my apex to only allow the ATO to turn on for 5 minutes at a time a couple times a day

My Smart ATO Micro failed after three years. The optical sensor had a water intrusion and it just kept beeping randomly. That said, it failed in the best way possible in that it did not fail in the on position. After three years I can’t complain, I consider it a good purchase.

Hey guys.. love the little nano @ 9:53.. just wondering which light is lighting the tank and which light arm? Thanks

I've had my SpectaPure ATO system going strong for almost 15 years. I would never spend this much money on something that would go out every year.

Always put in check valves on your auto line

I have the GHL float switch and have it automatically shut off if it pumps for longer than 30 seconds that way if my float switch ever fails then my profilux will cut power to the outlet preventing a overfill

#21 - When setting up your ATO if it has magnets that hold it in place, be sure you don't have something stuck to the magnet before you put it in the tank. I've been struggling with a tank for the last 6 months or so... weird things were happening, nothing seemed to make sense... I was looking at my return section to see if it needed to be cleaned and just happened to notice a small reddish-brown little nub sticking out from the magnets. I pulled it and found a razor blade.... It must have gotten on there when I was setting up the return section and cutting soft tubing for the return pumps to the bulkheads. It had been rusting in the water since I set it up about 11 months ago. After removal.. many water changes... things seem to be moving in the right direction now.

I have a 5g bucket as an ATO reservoir for my 90g tank, I leave enough room in my sump so WHEN it fails my sump will still be able to hold it.

Nice thing about the osmolator (and i guess other ATO's??) is that the pump power is just 12v (forget amps). You can change the pump out for a decent Peristaltic pump from ie kamoer which solves the issue with kalkwasser degrading the pump life and solves the issue with head pressure. Just check that the pump draws less amps than the controller outlet. If it needs more amps then hook up to a solid state relay and power the pump through that. Ive tried both and works great. Currently have the osmolator running a 240v pump through a relay. The original osmolator pump lasted about 1 year from new... not impressed.

What size resivor do I need for a 20 gallon tank?

Love the vids. But I've used the tunze nano for few years and the pump would always fail (Excellent customer service as it has replaced under warran) I would get anywhere from 6 - 7 months out of it in a reservoir filled with RO (No Kalk being used) so rather then keep dropping the 22.99 on a new pump I went optic eye for a new ato and so far still using the same pump 5 months in...🤞🏼🤞🏼🤞🏼🤞🏼🤞🏼🤞🏼

Where do I find the flow lock you’re talking about is it called something else also?

Great topic. What is the optimal location to place the sensors? The return section of the sump? the skimmer compartment? The Fuge? My biggest question is the best place to put floats and opticals.

Set up my ATO thing would go off every 2min, didn't even think of the siphon

Wouldn't it be a safer idea to have your RO water to keep your ATO reservoir full and then have your ATO set up for your tank? Then you can install an overflow line in the reservoir as a final backup that gravity feeds to a drain or outside. Also prevents the salt to components attached to constant water. For that matter if possible an overflow could be set up in your sump if it's high enough for gravity feed to a safe location.

Question (Not related to ATOs): What type of corals are in the tank? Specifically the tall green one and the purple one. Thanks!!!

Hey Ryan I was thinking about getting a Nuvo ext 75 gallon aquarium with APS stand from Bulk reef supplies but the people in my family are afraid that it can brake and flood the house, what’s the likelihood of that happening because I really want to upgrade but I can’t because my family thinks it’s dangerous for the house what do I do (PLEASE HELP) 😅👍🏽

I use a Pepsi Brand : Auto Top Off... Never have had a problem.

Been in the hobby 5 years and never added one because fear of failure! My salinity is all over the place and cant keep the skimmer running so its time! LOL! Does tunze nano have same safety features as osmilator 355? I dont think it does and dont want to spend 230 on 2 ATO's when I have a 36 and 20 gallon. It sound like even the osmilator can go wrong It dosnt have all the features you are saying to add on! What If bought a reefbreeders or something and added a float valve? I am a 62 year old woman and hubby isnt in hobby but pretty handy aroung the house. Can I add the float valve to any ato? What is the second best or two simple redundancy features thats easy to add? If I add 2 more plus what it comes with will I be safe if using a 5 gallon reservoir? PLEASE HELP this old lady reefer!

I see you have an alarm next to flow lock! I am so confused! Do I have to buy the alarm too? Or is this if you don t have an ato and doing a dyi version like one of the commenters said! He uses a bulkhead and tubing to his rodi and a float valve I am wanting to place order today. I wish you were open so I could call but last day of black friday sale. I rather get a cheap one and add some redundancy features or do what the commenter said with his dyi hook up and he said it never failed in 10 years! ! I need one for two tanks as well. I just spent a fortune on holiday coral sales and ebay auctions LOL If I buy cheap one I need float valve and flow lock and solenoid to be safe if running from rodi? You also mention a syphon break and check valve! some where in the video Do I need that too? What if just coming from a 5 gallon container and not rodi? What should I get if I buy reef breeders or another cheap one? What should I buy If I buy the pricey osmilator? What should i Buy If I get tunze nano for my 36 gallon? Seems to have less features and worse reviews with 3 1/2 stars! If you answer please tell me the easiest fail safes! LOL Not tech savvy and hubbys isnt either and he has no interested in hobby but will help when i need him to! Is the tunze nano still better then the reefbreeders or other cheap ones? It only has 3 1/2 stars but maybe people are trying to get away with using on a big tank!

I am not able to understand why one uses ATO? If it is to be kept aside SUMP then it is better to make a return chamber bigger and you will be having 40-50 ltr of water to maintain water level for a longer period. You can easily save money on ATO. I am using SUMP with 50 ltr of retune chamber and it is working fine. I need to fill it after 10-12 days. I hope I am talking sense.

Please do a TIPS & TRICKS for battling dinos!

Wait, I thought putting a glass lid on was a bad idea because it reduces gas exchange?

Would directing ATO water over the float switch and optical switch help with salt creep? If the eye won’t trigger when water flows over it for a minute or so, it seems like an easy way to help mitigate the risk of salt creep. I mention the eye mostly because they are mounted next to the float switch on the osmolator. Clearly flowing ATO input over float valves could only help.

Starfish keep getting on my ATO sensor and causing it to overflow lmao I’m not sure if there’s a solution for this

the osmolator is SO LOUD! Worst aspect of the tunze. Thinking of using my GHL Doser 2.1 to do ATO because the noise is really annoying.

quality industrial standard solenoids go a long way.

Been in saltwater for 27yrs and never had issues with anything said here, common sense is rare today lol

What is the circular nano tank at 9:47?

I don’t get it one video says to have turbulence on top this one says not to another video says no Top or hood better and says not necessarily. Ughhh. I’m never gonna get this right.

1. evaporation=growth=kalk, you don't want to reduce evaporation...i don't like this advice... 3. i've found float switches are FAR more reliable than optical sensors, which i always find myself cleaning frequently, especially the apex ones, they are horrible. I usually do low/medium/high with madison floats, I rarely have to clean them in my setups, so your example seemed extreme to me. I've only ever had to clean them in a tank that has no sump, because algae grew on it. 6. long-run timeouts are an important feature on an ATO to prevent over-sized reservoir related issues. 10. when using a pump in an ATO filled with kalk - put the pump in a shallow plastic sandwich tray, this will prevent it from pulling the sludge off the bottom and greatly increase the life of the pump 11. same as 3, i just haven't had to clean float switches nearly as much. The optical sensors tend to build up a film over them, but for salt creep to actually form on the float switch, frankly, i don't see this as much. Still should clean it of course, but, i find the frequency is much different. 12. Naw, I still say don't do that. I would sooner setup my RODI to refill my ATO reservoir once a week on a timer. I would never hook a never-ending supply directly to my tank. The failsafe here is to not do that, and rather, re-fill the ATO reservoir. And still have all the regular failsafes on your ATO in addition to that. 14. I reduce TDS creep by using my apex to control the flush. Once when it turns on, and once every hour there-after. I also have high/low switches in the RODI tank that prevent from short-running the system. I also have dual pressure zones - a separate pressure switch that prioritizes keeping my kitchen's RO booster tank up to pressure before filling my RODI tank. 15. Yeah, I get the hint, the ATK sucks. Even the V2, they still haven't addressed the FMM module going corrupt, it definitely is better with latest firmware update, but it still goes corrupt occasionally. I don't hate the V2 PMUP, but I hate the optical sensors and FMM. I've got 5-6 tanks off break-out-box based Apex ATO with madison floats, never an issue, but I refuse to use the ATK or rely on the FMM for anything other than leak sensors and flow meters. 20. 2 of my tanks have a closet next to them. That's all ya gotta do!

Get bigger sumps

why is that second guy there? he just stands there, nods, raises his eye brows and agrees with everything the other guy says.

Tell me I don't have to clean my ato tote for atleast one year 🙈🙈🙈🙈🙈

Guys, they make a one way valve for a reason for ato
