I have a 90 gallon Fresh water tank. It my first large tank. I have had 20 gallons in the past. but large tanks are new to me. it came with a emperor 400 and an eheim 2217. Should I build a sump for it? if so how big?
So do I run these filters or a sump or both. My goal in brilliantly clear water and one water change during the course of my lifetime
