best prefilter material?
I have a fine (0-1mm) sand substrate in my freshwater tank and I am worried about sand getting sucked into the filter intake.
What would be the best material to make a prefilter out of to cover the filter intake?
Or could I just raise the intake to mid tank level rather than low down near the substrate?
