I don't know. While most of the "experts" on the list prefer not to use UGFs
because they move the water through too fast for prper nutruent fixong, George
Booth, who is one of the more successful aquatic gardeners does occasionally
uses them with good success.
> Is the substrate two thick?
5 inches is pretty thick, but not too thick. For optimum plant growth you
need to get something more than just gravel into it. Laterite, local red
clays if available, and kitty litter are on the list of prefered additives.

isn't running?
Anoxic is not a problem, anaerobic is. The plants will transport oxygen down
the roots to use it as needed.

The pH and KH are just fine.

Peat will soften and acidify the water, so I guess it is what you are
comfortable with.

My thoughts are just leave the parameters alone.
