My neighbor sold me his 55 gallon tank and wood stand for 50 bucks.... in pretty much new condition, hes moving and dosnt want to take it... Im wondering what filter and air pump isnt the most expensive but not the cheapest...(not the best but not the worst) Its going to be a freshwater tank. Is the canister filter the best way to go there? I read alot of people have 2 filters why is this? is there not a canister or tank hung filter that can work alone and do a good job? On the air pump, is a Maxi Jet 400 powerhead pump good? Found one that pumps 106 gph and its $21.99 or is there a better way to go there? Would a single 100 or 150 watt heater work?? Well I guess those are my most pondered questions so far... The advice would be much appreciated. It is a 55 gallon.
