Too much Carbon?
Is it possible to run Too much Carbon?
I have 2 filters on my 65 gallon tank.
1 is a Fluval 404 with 2 trays full of carbon, and the other 2 are empty. no foam pads in the filter
the other is a Eheim 2229 Wet/Dry with bottom tray containing Seachem De-Nitrate, and the other has 2 sachets filled with carbon. this filter is running as continuos. not wet/dry
