Have had many PH issues due to co2 lowering ph. Have found balance with addition of buffer to bring up slowly for the past week from 7.3 to 7.75 now and still rising slowly. using Kalk in top off water to help maintain level and adding the buffer once a day to bring up. only issue now is alk is over 14 DKH but corals seem to be really happy now with PH up . I know buffer what causing ph and alk rise but is high alk an issue?
