My Alk has been low 7.0-8.0 and I am adding b-ionic. I have tried adding more Alk part 1, but no change. Is there a safe way to get my Alk up. My CA by the way is 425 and has been in the 400's since the tank has been set up. I don't want to screw up my param's and everything seems to be growing fine. Also can someone explain how a kalk reactor works and if getting one would help.
