Of coiurse I started with a 40g freshwater tropical tank and like d salt. However, now that I know much more about aquariums.... I'm curious about applying some of my salt knowledge to fresh. What I mean is that I have always liked the natural gravel, planted, tropical fresh aquarium and am curious about doing a large one. Say like 200g. So.... thinking like salt.... finner gravel to prevent ditritus build up (i know I can vacuum) Powerfull lights... say T5 setup to grow beautiful plants... tons of schooling fish... maybe even 2 MP40s on one end for a river like flow.... and a sump to run media and equipment and top of stuff. So what about it? any experience? Any setup you know about? Any good fresh water forums to go to for what I'm looking for?
