Just replace media a week sooner...
I get that but then I will be wasting over half a canister of media which I dont get why the PH drops when there is still 1.5 out of 2 canisters with good media

Any updates on your results from using a valve to control your scrubber? How much longer did your media last when compared to intake from skimmer cup without control valve?For the solenoid valve and pH control. I'll be using a 3-way / 2-position pneumatic valve (MettleAir 3v310-10-DC24) normally closed valve.
Port A will go to the skimmer pump.
Port P to the scrubber. (normally open)
Port R to ambient air. (normally closed)
Then connect to Apex via a 24vdc port.
If pH hits 8.4 turn off the 24vdc port. If pH hits 8.3 turn on the 24vdc port.

I haven't had a chance to hook this up on the tank that is up and running yet. I've still been pretty stable between 8.35 and 8.50 and the media still lasts about 60 days.
Rather than a catch can, I found that if you drill a small hole about 1/8" in the line from the skimmer cup that the condensation gets removed from the line. This allows the temps to equalize, reducing condensation, and PH is not affected. I did this right next to the connection at the cup.
I recently purchased the equipment to run my setup with a solenoid. My pH hovers between 8.2 - 8.5 since the installation of my CO2 scrubber. I will install the solenoid when my first container of media is spent. I'll not only compare how much longer this will extend my media life, but I will also track if using a solenoid to keep my pH between 8.25 and 8.35 would have noticeable reduction in my Alk and Ca consumption rate. Meaning is there a sweet spot for my pH value where I will find diminishing returns on coral growth rate with a higher pH. I'll use the consumption of my 2-part dosing as my measure for coral growth rate.I haven't had a chance to hook this up on the tank that is up and running yet.

Awesome! Do you know how much your consumption of Alk and Ca has gone up by since adding the CO2 scrubber?Love this thread, but of anectodal evidence from my own setup, I hooked my co2 scrubber back up about a month ago. 10” canister with the air supply coming out of the skimmer cup. Ph went from an average of 7.7-7.8 to now 8.1-8.2, and it was higher but I started dosing vinegar. Oh and so far the media has lasted almost 4 weeks. This is on a 40B with a nwb110 that I hooked a varios 2s up to
Awesome, can you post some more pics of the install. Also could you provide some detail on how you configured it with the the Apex?
I use motorized ball valves on my scrubber.
From what I was reading in another thread, solenoids stay energized all the time and can get warm... while these motorized valves only draw power when needing to turn the valve. (Also, I doubt solenoids really restrict much air flow, but I suppose having a larger pipe can't hurt.)
Anyway, Using two, I can have apex open and close based on the pH. Too high... pull "regular" air. Too low... pull from scrubber.
My pH increased. The old highs are now my lows. The fluctuation up and down is much tighter as well.
