They did release the video on co2 scrubbing and mentioned it doubled their alk consumption. I noticed the same thing in my tank. I use kalk along with co2 scrubbing to get my ph up. Before raising ph I would run my calcrx at a ph of 6.4. I had to raise my calcrx ph to 6.6 but I now dose almost 2 1/2 gallons of saturated kalk a day. Corals that wouldn't grow before have started to grow.Ryan from BRS is one of my friends. He was telling me a year or so ago about testing co2 scrubbing and the affects on Alk Consumption. Not sure if a video was ever made or not but the raise in ph almost consistently doubles the amount of Alk Consumption within the tank... meaning it absolutely increases coral growth compared to running the exact same tank with lower ph.
I think for anyone that has really low ph and you can raise it up another .2 or more, you would see a difference.
Yes the canisters are plumbed to go from one canister to the next. People say don't chase ph for a reason and I believe it's due to having your ph jump all around because your chasing it with liquid ph booster or you don't keep on top of whatever method your using and your ph goes all over. I wanted to raise it with a way that I thought would keep it consistent. The two canisters made sure I didn't have to throw away unused media just to make sure my ph wouldn't drop when it was used up.
Water in the canister helps the media last longer but I was hoping that since it pulls all the humid air from the skimmer that it would almost be to the same affect. You can see the tube looks gross from whatever moister it pulls in.
