I currently have a eheim 2217 canister filter on my 90gal FOWLR
tank. I converted this tank from a FW
3 weeks ago. However, now I am thinking about getting a sump wet/dry filter. I want to hide my HOB
skimmer and heater. In addition changing the filter medium in the canister was always a pain with the FW
tank. I would like to take the next month to design and created a DIY sump filter. My questions in this regards are:
1. If a buy a used aquarium from craigslist what would be the ideal size for a 90 gallon tank?
2. Will this effort save me significantly less than buying a new sump filter?
3. Does anyone of DIY designes to share?
