Change your Apex program to just shut off the regulator if pH gets to 6.3 (lower than that and it can turn media into mush). Watch it for a day and see where it settles out. If tank dKH continues to decrease than increase the PSI or bubble count to lower the pH of the effleunt. If dKH increases than lower the PSI or bubble count to raise the effluent pH. Do not set a high shutoff with the Apex.
