My two 20+ year old Rena XP2s are finally giving up the ghost. Came home on Friday to a puddle on the floor and a slow drip out of the power cord hole. It looks like the motor seal is failing and letting water into the head of the unit. They're way too small for my 210gal anyway, so before the second one also fails, I ordered two of the C-530 canisters to replace them. Anyone have experience with them? How do you like them? Rbishop I know you've been a Marineland canister fan for a long time, any thoughts?
