As I am new to the aquascaping aspect, I am curious as to how does one go about tank main? Specifically, I am asking with regards to the substrate. Coming from a reef aquarium with prior dealings with a community tank with easy to grow plants with an UG filter, it was practice to vacuum the gravel. I however haven't seen much mention with regards to doing so. Here I am asking, how does one keep the substrate clean and the detritus from building up?
