Dont you hate when you make a measurement mistake, setup the fish room, looks great. ONLY, i did not leave quite enough room be tween the 5ft and the 3ft for the 3fts canister (which i now have the replacement head for) Grrrrrrrrrrrrrr.
Soooooo now i will have to take the canister off the goldie tank to put on the 3ft, being a Fluval, it will fit into the space....and the canister that is for the 3ft will have to go onto the goldie tank, though i am debating taking the canister off the 6ft outside and putting on the goldie tank, but i will give the smaller one a go on the goldie tank and see how it goes.
