Hello everyone, im planning on buying a new 6x2x2 tank and will be keeping cichlids in there, the problem is i want to get the filtration right first go. im thinking of going for a fluval fx5, would 1 be enough? Also, could i opt for a sump instead or are they used only on marine? ive never had a sump so dont have any knowledge of them, any advice and suggestions would be greatly appreciated, lastly can anyone recommend a good priced 6ft tank and cabinet, ive had alook on the net and the price varies quite abit, thanks
