Korallin BioDenitrator / User Insight Needed

[GoVols]

Well, Kinda getting tired of carbon dosing my (ULNS).

I know I can hold down phos. with my GFO reactor.

So been looking at this unit for nitrates.

Can it hold nitrate at like 1ppm by adjusting flow?

Please list your pro and cons with this unit and this nitrate reduction method.

Any user input would be greatly appreciated!
