I have a 54 Gal
and I run a Fluval 406, rated for 100Gal. I also have an AquaC Remora S skimmer. My water is very clear. That's on my SW
tank. I started recently with this 54 Gal
and was told to double the size of tank to figure out the capacity of the filter you need. Mines not quite double my 54Gal, but the skimmer is running 24/7 too. I also have about 60# LR
. With freshwater you won't need the skimmer, Though.
