hmm but why is there a need to urh...maintain the canister filter so regularly? I thought filters were designed with ease of maintenance and all....and besides, I thought canister was made for "once in a two month maintenance." hmm.
I may however, buy another type of canister filter for marine. a wet/dry type for aeration, but I heard that isn't totally necessary as you can adjust the water blast bar or something. is that true?
lastly. filters with inbuilt temperature adjusters. good buy, or avoid like the plague? thanks! (=
