Pumps And Filters - Is What I Got Enough?

[Jonnyg]

I got me a 4ft x 1.5ft x 1ft tank, i have worked it out to be about 180ish litres. The system at the moment has the undergravel tray with a pump in the two back corners. I havent got no 'filters' as such except the gravel, is this sufficiant or do i need to add anything else??

cheers

Undergravel filters are okish if they are regularly maintained by routine gravel vacs.but they do have a tendency to clog up.

Whats the pumps output? I assume it's suitable for the tank size.

Personally i would invest in an external filter,run this on your tank for a few months then remove the undergravel filter system or the pumps running it
