I’m going to pick up some bumblebee’s for general house keeping. I never over fed the tank, but once they were in the water column they remained established. The got into the overflows and i had no idea how bad it was. 6 months it started getting out of control and at a year I was overwhelmed. I acid washed and then bleach soaked every piece of rock and im still working on the sand. Didn’t realize i had about 400 lbs of rock between the refugium and DT. As I mentioned earlier, I will QT everything as if its a fish for 90 day’s
