Hi All Have heard both but here is my situation, I have been battling dinoflagellates for a good while. I have resisted adding any chemicals to my tank. I have a faily large amount of flow in the tank according to my 2 flow meters water turns over 11 times an hour and I have a Gyre 250 in a 90 gallon. I saw something about CO2 and Dino's and they had good luck adding an air stone at the return pump believe it or not this has seemed to work.
My Question is will these bubbles hurt my coral? My wife like it witch my be a bad thing but anyway just asking
