I recently started up a second aquarium(29g) with sand instead of gravel. I really like the sand and am willing to deal with the extra hassel but I have started having problems with my power filters being used on this tank. After a few short days the filter begins to make a lot of noise until the noise becomes unbearable or the filter just stops working altogether. I have experienced this problem with a Marineland Penguin, an aquaclear, and a whisper power filter. Does anybody know of a way to correct this or a different filter I can buy that wont experience this problem? would a different type of filter like a canister filter fix this problem? Any help would be appreciated, thank you.....
