[APD] filters, nitrates, and myths?
the present consensus on nitrates being better than ammonia to keep
algae away, and such, has gotten me thinking on the use of standard
filter units (minus the charcoal) with planted tanks. In several places
it has been said that it is perhaps better to forgoe using standard
filter floss type filtering and to use something simple that just
collects the big peices and moves the water around, like powerheads or
such. But, based on the idea that nitrates are far preferable to
ammonia, then would it not be better to have a fair amount of filter
media? opposed to just moving the water around and depending on the
plants to take care of the ammonia? or something in between?
