Well i bought a 6x2x2 tank which is 850litres, it came with stand and a fluval 403 canister filter and a fluval 4 internal filter. The 403 blew up the first time i hooked it all up and the internal stoppped working last night!!! The tank is now only running with an aquaone canister (1200l\ph). I believe i wil need another filter because the aquaone doesnt pump enough on its own, any suggestions?
