I've got a really silly question for ya'll tank experts. We've got a basic 20 gallon freshwater tank that the kids have a dozen or so fish in. Nothing special. Seems like there's always debris and fish $#@! on the bottom and I'm constantly sucking that stuff out to make the tank look half way decent. Most of the pictures posted here have very clean bottoms. My question is whether there's an easier way to deal with all this fish $#@! than breaking out the siphon and sucking it out. I'd imagine that would majorly suck in a big salt water tank. There's got to be an easier way.
