Recirculating CO2 Scrubber Skimmer Cap

Skimmer CO2 Scrubber Cap

3D printed skimmer cap to hold bags of soda lime to reduce CO2 in the skimmer air intake. The top cap has two 6.5mm O.D. tubes protruding from the rim. These tubes should be attached to the skimmer air input. If your skimmer is not listed, contact me and I can add it. This is still in...

I actually got the idea when I was talking to @PeterC99. Didn't see it on Reef Dudes. How'd he make it official?
Mine works great.

Hi, I will need measurement (diameter) for the top cap from side to side. With those I can make your skimmer cap.

I'm curious @Projects with Sam how much of a pH bump did you get with this?

I'm curious @Projects with Sam how much of a pH bump did you get with this?

I would like to think I get at least a 0.02 to 0.04 pH boost but its so hard to tell because I change so much all the time.
I was unable to get above 8 before I installed it and now I've been able to hit 8.2. I've also increased my Kalk dosing as my reef's alk requirements have increased.
The media turns purple over time indicating that CO2 is being absorbed. Furthermore, I don't get awful skimmer smells because they're being recirculated.
My last refill I wet the soda lime too much so it joined together and the air was just going around it. It took me the longest time to figure out what was wrong with my reef; I could tell something was off; just didn't figure it out till I checked the cap and the media was still white a month after I refilled it (just the edges were pink).

Anyone know how to install a shut off valve for recirculating co2 scrubber

I got something like this:
then a 12V power adapter from Goodwill.
plugged into my Apex to power-up & open and let regular air in if Ph over 8.4
