Canister Filter as sump?

[canadianbudz604]

There was a thread about this same thing awhile bAck, but there is nothing wrong with a canister filter at all. If you keep the maitanence up on it, it works really good. The problem is without cleaning it, it will become a nitrate trap. Maybe someone can put the link to that other thread in here because it had some good tips about cleaning and taking care of the filter.
