I have an 80 L / 20 gallon tank with four adult goldfish and one youth, so I need a pretty good filter. I'm currently using a cheap sponge biological filter which is doing pretty much nothing, so I need to upgrade pretty quickly. The trouble is; I'm finding it really difficult to choose which type of filter I need.
There are certain conditions that the filter must come under;
- The filter must be cheap! I really can't afford to spend over twenty pounds on a new filter.
- The filter must have a visible effect! I need the filter to actually trap the dirt/waste so it can easily be removed, not just drawing the waste to a particular space.
I think I need a mechanical filter, but I'm not too sure.
I'd also be using Amazon.co.uk.
Can someone please point me into the right direction?
Thanks.
