hey, i have a question, since you were on the question of copepods. about 5 months ago i did something which basically killed off my tank. i put something in the tank which deprived it of oxygen, long story short ALOT of things died, so im not sure if my 85 lbs of rock even has copepods. does the ceato have copepods on it? will the ceato and soapdish work if i only have very few?
