Alright I got me a 5 stage rodi unit. I’m super stoked about that! I am wanting to upgrade my filtration. Right now I have a 4 stage canister filter with sponge filter floss and two trays of ceramic media. Should I go with a sump or another canister. I am waiting on my 2 little fishies reactor to come in so I can make it into a Chaeto reactor for nutrient export. Suggestions on filtration would be more than welcomed.
