—Back in Feb, the pump started making noises and didn't seem like it was filtering the tank. I decided to unplug it, to take it apart and clean it....but then both o-ring and the rest of the pump would not fit back together. Because of this, I had to drain the tank. The pump did have sand in it and I am wondering if my sand grit is too fine. Whenever I would siphon the tank or change the water, it looked like a sandstorm.
—The issues are still the same as before with the noise level, drain issues, filtration, and potentially the water level being too high. Obviously, I want to set the tank up for my bichirs. Sorry for the long post.
