thanks JB NY but I am not running a calcium reactor. For the last year I have been using Randy's article on Solving alk and pH problems. I am due for a water change---maybe I should start over using the b-ionic two part system and try to bring stability back to the pH.?
Is a big flucuation in pH a problem for SPS corals or should it just be ignored and worry about alk calcium and magnesium(those are very stable right now)
