You do not have to use the carbon insert in an aquaclear filter. Just use 2
foam inserts instead of 1 carbon and 1 foam.

works good

Hi,

I have 20 gallon planted tank. Read many links that carbon in filter
removes
irons and trace elements from water. This does not help the plants. The
dynoflo-2 uses a filter that has carbon attached to pad. Is there an
alternative filter that i can use that does not have carbon.
