+1 for a Neptune PO4/NO3 auto tester

Instead of a solenoid, I use a 3-way motorized ball valve. It stores a enough power in a capacitor to close itself when power is cut, so it only used electricity while it's opening instead of keeping a magnetic coil going and getting hot. The path of the airflow is also a lot bigger than other solenoids I've used.

Neptune! BRS! Common guys! Let’s make this 3/8” control solenoid!

I bought that Ice Cap C02 scrubber and the media never changed colors. I don't know why but I just figured that I had no c02 in the room. So I just eventually unhooked it. I had it set up to the skimmer silencer to the c02 scrubber

Another mistake is connecting the skimmer to the wrong end of the IceCap or other CO2 media. The IceCap in particular is confusing on the direction of the airflow.

I would love to watch a how to setup up a co2 scrubber with the ph meter/controller.

I have my tank in my garage ph in there is amazing

Thanks I understand C02 a lot more 👍

I want a Trident but for nitrate and phosphate. Can we ask for that too? Also, I would like a “low flow” flow meter to track how much calcium reactor effluent I dose. Something that can measure down to 1ml/min.

The funny thing is the canister is shaded the same as the color changing media. So it's really hard to tell. Mine looked off white but when I dumped it out it was violet.

I put a CO2 scrubber on yesterday with 8.0 ph. Today the PH is 8.2. I have never seen 8.2 in my house. I only have a CO2 pen but I am monitoring every couple of hours. If it goes over 8.3 I will sort out a controller too. Years I have been looking at my tank's biology and all along its nothing but atmospheric CO2 causing the low PH. I listened to a lot of hydrodramatics to get to the right solution. Kalkwasser was not very effective at raising the Ph in spite of an open top and 10 liter per day evaporation rate and its much more work to maintain that system than it is to spend 5 seconds plugging in the scrubber. Its been on my system for 24 hours now and I am completely sold on its value.

I’ve been asking for that valve since before they came out with the trident….rep at the booth didn’t say the were working on it.

I dose kalkwasser and use up the CO2. My pH is in the 8.2-8.3 range, even with a well sealed house.

NEPTUNE please make the 3/8 solenoid valve 🙏🙏🙏🙏. Been searching for this for a long time! In my use case I would simply use it on a timer to run it during the night time!

3/8 three way valve please!

What is the Solenoid model number at McMaster Carr?

3 way Solenoid valve works grate

Would an option be to use an air pump? Say, air pump to co2 scrubber to sump tank. Just put the hose in the water. In the video you mentioned buying a solenoid and wiring it into a timer or a controller. Or just turning the skimmer on and off. The first sounds a bit complicated for the average person. For me, I’m a tech, so simple enough. The second, them skimmer pumps are pretty expensive. Turning them off and on will kill the life expectancy, and also that my not be an option for some. An air pump is dirt cheap, what $10-15 bucks? An Alexa plug is about $10, and most people have a few sitting in a drawer not being used. Do you think that would work? Monitor the tank every few hours for a few days to a week. When the PH drop have the air pump come on. Just an idea outside the box.

I made a HHO generator and discharged the Hydrogen outside in a high wind area and the pure O2 I plumb into my air intake with a ball valve to adjust the amount of pure O2 going into the protein skimmer... Ph ~ 8.3/8.4.... 😉

If your running a recirculating system. No need for water at the bottom as the intake has plenty of humidity from type of skimmer.

Hey you guys didn't provide a link or any specific information about which Mcmaster solenoid you used....their site has a bunch of them....not sure which one of them to get, not to mention they're pricey so I don't want to spend more for a model I didn't need. Thx.

My skimmer has 1/4 in tubing and changing will mean modifying the skimmer. It seems if it's working why change it? If putting larger dia tubing means needing a solenoid to limit operation. It's already limited. Since adding diy scrubber my CO2 is now back over 8

Mistake #21, not buying the 5 gallon bucket of CO2 scrubbing media to save half the media cost.

Currently running a reef octo 200 int. Running the pump below 50% causes the air to stall out after a few days. I intially tried running 2 10" canisters with 3/4inch tubing. Kind of disapointing that the pump wont support this config. Only seams to work reliably if i leave the canister unscrewed a little bit. Wish i could run the pump at 100% without overskimming. Maybe a new type of skimmer/reactor is in order so we can peg our PH with out overskimming.

They have a device that shuts off your skimmer just like a auto top off celiniod that would shut off the skimmer .

Just made one only use 300ml for 8f tank volume its lasted a week gonna be an exspensive exsperiment disconect it at night to let it drop like my tank would do anyway

I tried the recirculating but the condensation that collected in the hose and scrubber chamber hurt the performance of the media.

gosh darn it I bought my scrubber from BRS last Tuesday!!!

um yes this is nice and all but what if you got nomore room for groth

I have to run my co2 scrubber 24-7 . My.ph barely gets to 8 . It dips to 7.8 at night with the c02 scrubber. Im kinda disappointed in it. Maybe if I had a refugium along with it it would work better but I run biopellets in a reactor. I am running it recirculating so it's not sucking room air. I was also thinking maybe my skimmer doesn't suck enough air. It's a eshopps 125 . On a 65 gallon mixed reef

Hello BRS, Is it possible to run Ozone and a co2 scrubber? Correct me if I'm wrong, doesn't each one typically go to the protein skimmer air input? If injecting ozone, what would the additional benefit of Co2 be? Is one better than the other? Can both be done successfully?

Can we get link to the 3/8 valve from McMaster? I am manually adjusting a valve now. Open all the way after I change, then slowly close as media is spent. I tried the recirc trick and it was to much suction close to the skim foam even with a safety sponge to pop foam.

if you own a kiln or have access to one you can probably regenerate the media.

where do i buy airline t splitter?

Could the distance from the co2 scrubber to the protein skimmer be a mistake? What is too long? If you had an aio tank, could you put a scrubber in the cabinet and run the line up to the skimmer or does the scrubber need to be situated right next to the skimmer?

Can you not just use a neptune solenoid valve with increasing/decreasing from 1/4 to 3/8 so that you can dyi a connection to the scrubber?

The next thing will be to add an O2 concentrator to the skimmer to mimic the O2 levels in tropical oceans.

But what if your using ozone and want a co2 scrubber on the intake of the generator? Aren't most of them the standard airline tubing size. Would that choke the skimmer.

compare with inject ozone gas pls

Of course you have a sale one week after I purchased one 😔

I was thinking of buying a cheap one you have but this is sounding complicated for a woman reefer! LOL. I am not high tech in the slightest! Do I have to have a ph controller, solenoid valve and all that other stuff?

I am drawing air from outside the house though hoses to the skimmers on my two tanks. My PH for both tanks is in the 8.20s. Would there really be any benefit of running a CO2 scrubber on both tanks?

Would you still use a CO2 scrubber and kalkwasser? If kalkwasser also raises the pH, wouldnt the combination of these two be too much?

My ph gets up to 8.56. At which point should I start to be concerned about ph being to high? Thx

Can a co2 scrubber be implemented somehow in an aio with no protein skimmer?

So we just need a few trillion tons of the stuff so we can scrub the CO2 out of the oceans to save the reefs!

Recirculating the same air is also going to reduce the amount of oxygen you will get into the water through the skimmer. It’s a double edged sword

First mistake for me was purchasing the co2 scrubber. Did nothing

Man that anthias looks like its eye is about to explode that a fluke on his eye or something hope he is doing better now

mistake number 1. Wasting my money on one of these in the first place. This thing did absolutely nothing for my tank. Never budged the PH up even a single point

There has to be a better way

Lols to incorrectly writing CO^2 throughout the slides. Also it's a bit of a gimmick here to say the skimmer is always performing more gas exchange vs water surface gas exchange. This is dependent on surface area of the surface, whether or not your tank is covered, how turbulent the flow is of the water surface, vs. the air consumption rate of the skimmer. Suggest doing a couple quick calculations here before spending money on calcium hydroxide media.
