I figured this would interest some of you, thought i'd post it here since keeping polys and being overstocked go hand in hand.
A few of us have been messing around with nitrate reduction methods on the attached thread. Wealth of info

Plants help reduce nitrates but from my limited understanding of it they arent too efficient. Maybe on a lightly stocked tank but whos lightly stocked ? Lol

can better explain.
Anyway ive had the denitrate filter set up for a week im not ready to call it a success as i did lower feeding this past week but it is showing promise. Nitrates were in the red prior at about 40 to 60 ppm. Today they were slightly higher than 20.

can probably better explain how it works but the low flow creates a low oxygen environment which allow anerobic bb to cultivate and consume nitrates.
I still have some tinkering to do with the flow rate but heres what mine looks like. The multiple towers arent needed just figure what the heck why not. 1st tower is filled with mechanical media, 2nd is half filled with seachem denitrate (reg pumice stone will do) 3rd tower is completely filled with seachem denitrate.
Last pic is a ball valve attached to a 120 gph pump adhusted to 21 gph. Ideally you want below 50 gph
