Ca-PO4 bond cleaving!!!...........OF COURSE!!!.....I was just about to mention that....*lol*.....That's pretty heavy chemistry man but I think I understand....that zooanthelia is some funky stuff....but seriously,..that does make sense....and I do have a phos. test kit,...I have been preoccupied with my Alk.
So, question 1: Should I shut down my 2 little fishies phos. reactor or just chill with the Phosguard
question 2: Did you used to work at Aquatek??
BTW: Increadible tank project you have going....was looking at the pics. Outstanding woodwork!!....Is that an acrylic tank?? (Guess thats 3 questions)
