I was looking for a new canister filter for my living room tank because I don't like the idea of a sump in the living room.
And I seen that XP4's are about $150+ship on ebay. And they have a listed flow of 450GPH.
BUT then i read that filled with media they only flow 190GPH.
So is this true
450gph listed flow rate but only 190GPH once filled?
