I have 65 gallon tank which is fairly heavily stocked... it is currently filtered by an eheim pro 3 2075 filter... the return from that has a bypass installed which also feeds a fluidised bed sand filter....
I was thinking about taking the sand out of the fluidised filter, filling it with sintered glass media (bio max, or similar) and using it as a nitrate filter instead by running a super-slow flow through it...
The eheim is filled with ceramic rings, ehfi substrat, biomax sintered glass, and filter wool.
What do you think guys? does the sand filter add enough on top of the eheim that it's worth keeping? or switch to Nitrate reduction?
