i've always used mechanical filtration in the form of sponges and filter wool. and a thought suddenly came into my mind.
i know mechanical filtration is good cause it removes all the unsightly dirt particles in a tank, but i'm also wandering, what if your corals or clams or shrimps start spawning, and from what i know, the little coral, clam or shrimp babies are really small and float around, wouldnt they get stuck on your mechanical filtration and die?
would you guys consider removing your mechanical filtration if your live stock was spawning little plankton sized stuff? or how would you go around this problem?
