long story short, i just started working as an aquarist for a small company, i service about 15 tanks a week, i'm new to reef keeping (mostly cold water experience), and one of my tanks has a MAJOR aiptasia issue. I"m talking thousands and thousands of them, its a 12 foot tank and its gorgeous but the aiptasia is out of control. i'm aware of berghia but i think i'd need hundreds of them which isn't cost effective. i've got one copperbanded butterfly and he probably does some work but obviously not enough. i know i need another butterfly or two. about 50 peppermint shrimp were put in the tank a month ago and very few are left, i have a feeling a fish had some nice snacks (ie. harlequin tusk). my stategy has been kalkwasser injections to individuals, very time consuming although it does seem to be working. i had read however that you shouldn't inject but rather leave the KW on its oral disc/tentacles. is this true? i have injected and it seems to be working but does this cause the aiptasia to asexually reproduce before it dies making the problem worse? i also worry about pumping too much KW into the system and raising the pH to much. granted it is a large tank and i've been monitoring pH but these 3 hour sessions of injecting seems like a lot of KW. any help or suggestions would be appreciated. thanks.
