I have zoa's overtaking my return. I have zoa's overtaking my tank, also, but this is inhibiting flow. They're also causing weird currents and disrupting the sand oddly. I've taken the return pipe out and soaked it overnight, outside, in 50/50 water/vinegar. It's pretty cold out, as well. But it looks as if I could put the pipe back in the tank and still have healthy zoas. Any suggestions?
