Hi all.
I quite new to this hobby and need a bit of advise.
I had a 25L tank for goldfish with sponge filter. I now have upgraded the tank to 70L. I have put the sponge filter in the new tank but am noticing it doesn't pick all the waste that falls on the sand.
When I got the 70L it did come with a hang over the back filter.
If I add that aswell would that be too much filtration (if that is a thing)
Many thanks
