IceCap Co2 scrubber installation

[drtechno]

Ya that’s how I have mine as well. Pulling thru skimmer. As far as what size tubing, it’s whatever the typical vinyl tubing is at Home Depot for evacuation pumps. Looks like mine is 3/8” ID

Here is a pic of my wonky setup with my moisture trap before it

It could hook to an air pump but for best results your skimmer intake should pull from the scrubber.

I’ve got a nano tank without a skimmer. I’ve read in other threads that people have had some success with a pump and an air stone.

I know this is an older post, but I came air as I am having an issue and your post here got my attention. I have a Reef Octo Hob 2000 skimmer, and purchased a small Ice Cap scrubber. When I hooked it up, based on what little info I confine, my skimmer will not operate correctly when hooked up to it. It is still making some air bubbles, but not enough umph to get the skimmer goin. Any ideas? Do I have too much media in the scrubber? Can’t really change the pump on the skimmer. I am at a loss.

You could try taking some media out and see if that helps..

I got it squared away, but thank you. It actually had just a bit too much water. I only had 1/4” in the bottom, but apparently that was too much, cuz it is working fine now.

Came across this thread as I am hooking my Icecap co2 scrubber. According to Coralvue's website, the BRS video is doing correctly (e.g. attaching the outside tube to go to skimmer). It makes sense, since you want the air (possibly with help of an air pump) to go through the middle tube, through the media, through the little bit of water on the very bottom, and then out through the outside tube to the skimmer inlet. No?

Correct… you skimmer needs to Inhale from the co2 scrubber basically. Don’t count on the ice cap media changing colors when it’s depleted thou! If your oh is dropping it’s exhausted.

did you see an improvement when switching to the middle port? @iamacat

the problem is the media doesn't get any moist air since dry air is feeding in from the outside

I tried the outside and did not see any improvements, going to try middle

its absurd icecap did not include any instructions anywhere

 

[H.E. Pennypacker]

BRS video is wrong

I contacted the manufacture CoralVue who stated "The output is the middle port."

 

[iamacat]

Yes it resolved the issue. Only way it makes any sense

In my original post I included the reply I got from BRS when I sent them my analysis. Brad confirmed

How do we get water inside icecap co2 scrubber if you dont mind me asking

 

[125mph]

Every video I read I saw says to use the side port, as does CoralVue's website:

Just connect the tubing from the air intake of your protein skimmer to the output side of the CO2 scrubber. You may be able to remove the silencer from your protein skimmer. Next, remove the lid of the scrubber and fill the reactor with IceCap Carbon Dioxide Adsorption Media (or your preferred CO2 absorbent media) and place it back inside the scrubber.

I just ordered the scrubber so I will have to test both the center and the outside side.

 

[125mph]

I got it installed using the outside port and immediately see the pink media is turning white, and also see ph is rising.

I did out 10ml of rodi water in the chamber .

 

[Chenko]

Just confirmed with CoralVue support, that the Output Port where we supposed to connect the tube going to the skimmer's air intake is in fact the MIDDLE one.. not the outside one. Asked them to specify that in instructions since they just say the output port (but not which one of the two). For those who still doubt where to plug it in. @125mph try that as well.. I am curious how much better it gets with wetness through water. Also, @H.herry I added 10mg of water using a syringe through the outside tube (the one going all the way to the bottom). Now that I hooked everything up correctly.. I saw about .15-.20 improvement in my PH.

 

[125mph]

Will give it a try. Right now using the outside port, my ph high is 8.3 and low is 7.8. Prior to using this, high was 8.1 and low was 7.6.

Will report back in a few days.

Graph shows started using just 2 days ago.

 

[125mph]

Using the center port definitely not working. My highs sank 2 days in a row from 8.3 to 8.2 and then 8.1, and my lows sank from 7.8 to now 7.7

Without the scrubber I was at 8.1 and 7.6 so will be sticking with the side port.

Did you refill the canister with water? That is a daily task (which NO ONE TELLS you). I found that on my own because it's dry inside my house.

Yep, thats the first thing I did. I also checked this morning to see if there is any water left in there, and there still is.
