Second Filter

[pradeepcec]

Hello people,

I was thinking of adding a second internal filter (tetra whisper 10) for my 20 gallon topfin tank that has a Topfin 20 HOB filter. I am thinking of doing this because the Aquaadvice website says that my filtration capacity is 98% and my stocking level is 75%.
I plan to add another 4-5 fishes. (Currently have 6 xray tetras, 2 panda cory, 3 mm platy, 1 netrite and several small pond snails)

I think useful to have a second filter to make cleaning easier (although harder to find room on small tanks).

I did add a fluval 20 filter but I have kept it at minimum capacity.
