Bare bottom tank here. I don't like cleaning the detritus that builds up. I've been meaning to fashion some sort of vacuum cleaner to do it without doing a water change. once that's solve I will be golden!
You can place a powerhead to keep it circulating to be collected via filtration. Mine collects in an area and every once in a while I'll siphon it out when I do a water change. Not doing many water changes these days anyways so when I have to it helps me stay in tune with the tank.
