How many use them? Everything I read has very conflicting information regarding ph and whether or not to test for or attempt to rectify low pH. Many say it is fine to run a low pH system, and many others say you must correct pH to achieve healthy corals and good growth. I find it hard to decipher all the conflicting information out there, yet we're concerned about acidification of the oceans and mass bleaching events.
I run 90 gallon with sump. Alk is 8-8.5 using soda ash as my supplement. Open tops and skimmer run 24/7. My pH with my probe averages about 7.9 at night and 8.05 during the day. Corals seem healthy but growth isn't anything to brag about. My euphyllia always have baby heads but I've never seen them grow into full sized heads.
Should I invest in a co2 scrubber? Can there be any possible negative effects from adding one to the system?
