Ill filter it with an econobead 60, one sipaxtank converted to moving bed wit 500l k1 and some large showerfilters.Wow keep us updated with that sounds like a project, what would you filter it with? I seen some really cool filter Ken just posted would probably be perfect for a massive system like that. I think it’s called the Nexus 320. Meant for overstocked Koi ponds.
