Thanks for the comment. I need to add a 175w
metal halide bulb in the center of the tank, but that's another thread. Since the water falls 24 inches into the overflow, and I have a 6 inch pipe installed, that's 18 inches. I was thinking about adding an 18-20 inch pipe with a 90 pcv connector and see what happens. Make sense? I was going to add a strainer straight up with a filter that slides over it and a tube straw down the center to keep the gurgling nosie down, but I think over time the filter will clog and it'll be a pain. Besides, everything is strained through sponges in my sump anyways.
