OK, my 90 gal. refugium is outside plumbed to my 30 gal. half circle tank(cycling as we speak )30 gal. inside. I have cheato and 20 7-8" red mangroves in refugium. I'm doing my homework before proceeding, I would like to feed(day light hours) CO2 in refugium through the air not into water, I don't use air pump into refugium to reduce gas exchange , increase CO2 to higher levels 500-700ppm. Question:
Will CO2 enter water if CO2 is circulating in air within refugium. Will also have air system to exhaust it out. Please help
