Help with nitrates

[quote=makana;765933]I have a shallow sand bed that cleaned up with a gravel vac.
I run filter floss that I change every other day.

Why are you cleaning the sand with a vac or cleaning it at all?

Leave the sand alone. Constantly disturbing the sand will cause problems with your nitrates. The idea of a sand bed is to produce natural nitrite/nitrate reducing qualities with pods, worms, bacteria ect....

Ditch the floss.

If your nitrates still remain, start slowing dosing vinager to add nitrate reducing bacteria to the system.
