QUESTION:We'll soon find out. I just finished my new bio-filter. The spray bar
sprays onto two of these mats. I think they are just plastic.
ANSWER: I see in Home Depot a blue furnace filter that looks like scrubbing pad. This
is the wash and reuseable type. I think of using this as a filter media but
wonder if the material is toxic to fish. Anyone has experience with this. If
it is OK for fish, it would be a big bargain since the price is 10 times less
than the filter mat.
