I'm preparing to set up a CO2 scrubber, and I have some questions...

[Dom]

So I've been researching the addition of a CO2 scrubber to my main system, and I only see upside to adding one.

If I understand correctly, a CO2 scrubber is deployed between the protein skimmer and the external air source. The idea being that air for the skimmer is drawn through the CO2 absorbing media and into the skimmer.

But my skimmer (ReefOctopus 110S) air intake is a white knob with two holes to allow air to be drawn in.

Is there an aftermarket attachment? Is there an attachment that is part of a CO2 scrubber kit? Do I have to rig something?

Appreciate some guidance.

Thank you,
Dom

Pictures would help. Online photos are not showing the air intake clearly.

Have you talked with customer service at Reef Octopus?

I have the same skimmer. The white hose from the skimmer venturi goes into a hole on the side of the red tube that the white cap (silencer) is on... i don't remember if the hose actuallly attached to anything inside that red tube or to the white cap, but the white cap (though tight) i don't believe is glued or anything.

Either way, you can either pull the white hose out of that hole or pull the white cap off to access the end of the tube. I just pulled mine out through the hole Once you have the end of the tube either connect to the scrubber directly or what i did was add an extension onto it using a barb connection and another piece of tubing...

drill a hole in the cap of the silencer and attach the tubing to a barbed fitting.

i cut the picture because my sump is filthy…



you can PM me for guidance if you’d like! i did a recirculating skimmer for my reef octopus classic 110-sss as i assume you have as well

My idea was to cut the white tubing and insert the CO2 scrubber there. The challenge is making the connection between the tubing and the reactor holding the media.

I recently gave the skimmer a cleaning. Under the white cap, are two rigid plastic tubes, one for each of the two holes on the cap. Those two plastic tubes go in the end of the hose.

No, but I was going to reach to to BRS. Their support people have always been knowledgable and helpful.

FishOfHex has a couple good videos and also sells the necessary pieces.

yup! i got his recirculating kit and just found a regular 32oz container as the moisture collecting cup

i used a kynar barb from brs ( https://www.bulkreefsupply.com/ozon...D=1770&indexName=brs_prod_m2_default_products )

and the white silicone tubing ( https://www.bulkreefsupply.com/whit...D=2869&indexName=brs_prod_m2_default_products )

I believe it's 3/8" - just the white hose from skimmer to kynar barb to silicon tubing to scrubber. The sillicone tubing fits easily on an icecap scrubber. I also have the reef octopus scrubber and the silicone tubing is stretchy enough to fit over the barbs on it as well.

Yes... I was thinking I could do something like this too. I wouldn't have to damage the hose.

Definitely a cleaner install with a hose barb to the cap.

also it’s less than 20$ shipped to get a replacement air silencer cap from reef octopus. it’s only a matter if they have any in stock(i did have to wait like 2-3 weeks for it to go back in stock. and it took 4 days to arrive)

Now I'm thinking that I could use a coupler and extend the silicon tubing out beyond the cap (eliminate the cap) and into the media reactor.

You can - thats basically what i did - the red tube still functions same and limits amount of water exiting the skimmer - the tube was just a compact location for them to build a silencer into it... you can see the hole in red tube I pulled mine out of - next time i take out skimmer too fully clean it i'll probably go through the top and just leave the cap off like you said

my scrubber is on opposite side of stand - i have a few feet of tubing added on and as long as tubing isn't pinched it doesn't reduce the airflow any

reef octopus has the lids that do this on BRS. I have been thinking of getting one and hoping it fits on my skimmer

I saw that lid, and I have a 110S. But after starting this thread, I've learned that CO2 scrubbers are about removing CO2 to raise pH and not about elevating oxygen.

I thought about running one simply to see if it helps the tank.

It does the intended job. If you want o2, i would go the fuge route. I’m sticking with the scrubber until i decide it’s not worth the money and my next move would be Kalkwasser.
