I feel I am getting close to a stable chemistry (Taylor K-2006 & K-1766). I am chasing a rising PH but only need to add every few days now. I may back off on pump and swg run time some to see if i can still keep FC in range without driving up PH. The TA is up there and I have done at least 3 cycles of PH to 7 and aerate so far. It does not seem to have an effect other than the rising PH. We have no rain to catch and use as replacement water unfortunately.
