I added 10 turbo snails when I first started this thread and honestly I am almost clear of RTA. I also have a tuxedo urchin, emerald crab, and Striated Surgeon Fish in the tank that all seen to pick at it, however these critters were there before the turbos so I account most of the irradiation to the snails.
I do not have a calcium reactor but have been running GFO and Carbon in the BRS dual reactor. The lights I have are two Radion 15s and I run a nyos 220 quantum for skimming. There is a small refugium in the sump (~1-2 gallons of volume) that I have chaeto growing in but I havent seen much growth there so I believe the common denominator was the Turbo Snails.
I was not dosing anything during the time between my adding the 10 turbo snails and now and I never manually scrubbed the rock work. I am now dosing for alk and am using NO-POx to reduce my phosphates.
I have before/after pictures I will post soon. Hope this helps anyone else dealing with this nuisance.
