Ok i am getting a 75 gallon tank, i heard there is a way u can set up the tank so when the fish poo the power head or something will flow the poo off the bottom of the tank into the filter????? is that right??? i want to set it up so i don't always have to net out the fish poo, i do weekly water changes, but still i don't want a bunch of poo floating around the bottom of the tank ........ so how do u set that up?? Also i am getting a new filter and everything so if u guys can give me some input on what brands or what filter to look into that would be great, thx guys!!!!!!!!!!!!!!
