I've been using All-for-Reef for months and my alk has been stable. Two weeks ago I added a UV light to my system, which seems to have affected All-for-Reef's effectiveness. My alk continued to drop all the way down to 7.3 (just taken 20 minutes ago) even after I upped A4R dosage last week. Does A4R have any known incompatibility with UV sterilizers? I understand that how A4R works is it contains something bacteria feeds on and that the product of this process increases the alk.
I did add five or six coral frags three weeks ago but I don't believe they would have increased consumption by this much.
