I'm rearranging some tanks and starting over new and fresh and I want to get some ideas on how I should filter these 2 tanks with what I have already. I'm trying to do it the most effective way so I can sell whatever I don't need to use for a larger tank.Tanks are 90 and 75g.Filters I currently have- 2 Ac110's, Xp4, Xp3, Ac201 powerhead and a little via aqua powerhead. How would you filter these tanks?
