Hi,
A while ago I was in a creative mood and I build myself a filter. It's a cylinder with a volume of 0.85 liters and I filled it up with lavarock. In the middle I placed an airlift with a small tube, the opening of this tube is all the way in the bottom of the cylinder, such that the water flows through the lavarock and then out of the airlift.
I know this is not an uncommon way to make a filter, but given the size that I uesed,
would it provide sufficient filtration for a 50 liter tank with a trio apisto's and some Nannostomus?
