I have a few of the aquaclear sponges that i cut and slid over the intakes to a few powerheads and one that came with the intake in my overflow box. Everyfew days to a week the sponges turn brown to orange brown and I clean some of them but i notice that the sponges have a ton of copepods and bristleworms and other stuff. Is it a better idea to leave the sponges on and let the copepod and bristleworm populations grow and possibly feed off the detritus? I thought it would help to have copepod safety areas to continously feed my mandarin and sand sifting star.
