I own (2) emperor 400's on the back of my 55 gallon tank and want to know if I should take off the bio-wheels of the filter because my nitrates last night were 20-25ppm on my testing,
someone I think from another thread had said something about the bio-wheels being the cause of the nitrate levels ???
Is this true ???
