I have a 55G Saltwater FO
tank with an Undergravel filter running 2 - 150 PH
a protein skimmer for 100G, and an Emperor 400. I want to replace the Emperor with a Wet Dry filter and have 2 options. 1)
buy a Wet Dry with a BIO AREA of 2.4 GAL
of 8.75 rated for 75 gallon tanks or 2)
buy a Wet Dry with Capacity 120 gallons and BIO AREA: 3.3 GAL
. SUMP GAL
If I take option 2 I will have to modify my tank stand to fit it so I would prefer option 1 if you all think it will provide enough filtration. Thanks for your help!
