First of all, I run several smaller cubes between 12 and 50 gallons including 2 JBJ Nanocube 28 HQI's. All of my tanks run identical PWC intervals, dosing schedule (amounts vary obviously), and have similar stock lists. Mostly SPS's and zoas.
One of my JBJ 28's however drops 2 full points Alk (dKh test) from 8 to 6 between daily dosing of 2-part (BIG dose too). Other parameters are ROCK solid. I don't want to dose heavier and chance stressing my many SPS's any worse than the swing already does. All corals seem perfectly happy as do the clam and many inverts in this tank....but I know this swing can't be good for them.
SG 1.026
pH 8.2-8.4 based on photoperiod
CA 425
MG 1300
I tried a local forum with no luck. Even had members come over to test my parameters becuase they couldn't believe Alk could drop like that with pH, CA, and MG staying constant......but it does. Any ideas from you guys?
