Hello, just a quick question. im going to save up and buy a fluval fx5 but my current set-up of filters are not picking up most of the waste on the floor, so i was wondering... Substrate or no substrate? im running a fluval 205, fluval 4plus and eheim 2013 on a 100g 5ft tank (i know its not enough) with 1 Oscar 2 plecos and 1 blue acara.
Thanks
Thanks
