black spots on live rock in QT tank
i recently noticed black spots on live rock in my QT tank. parameters
i did have a damsel that i was QT'ing for ICH before moving to the main tank. no chemicals used. PASFURS suggested method of garlic, temp and low salinity was used. The damsel is happy and healthy in the main tank, but the black spots remain. My main concern is that i have no direct lighting on this tank, just a hang on filter, a powerhead and a heater.
Any ideas, is the algae good or bad do i need to cure before adding another fish to the QT? I am wanting to get a Pygmy angel this weekend and want to QT. please advise
