what is the best filter for a discus tank
hi
I am thinking of doing up my 6ft as a discus tank
I have my 4 discus a pair of blue rams and 20 Cardinal Tetra
in a 4x18x20 right now but would like to go bigger so I can put more in there
I have 2x6x18x20 tanks
1 has a sump that will do 3500L a hr
and the other has eheim 2217 and a 2228 running it
what tank would be best for them
both tanks are the same size
I like to have 6-8 discus and the other fish in them not looking to breed them
thanks for the help
