i'm not sure if there is a thread of this already. i was wondering what kind of filter to use with a sand bottom. wouldn't the sand do damage to the impeller of a normal filter? i think i read that somewheres. thanks in advance.
Howdy,
If you use a big canister filter with the impeller on top (e.g. Eheim), you will have no problems. The sand will settle on the bottom of the canister and will never make it thru the media, against gravity, to reach the impeller.
Note: On the all-hailed FX5, the impeller seems to be located on the bottom. Although I have yet to see a dissembled unit, I assume that it is prone to damage by sand.
