Please forgive the late response....been building a new kitchen and I'm finally seeing the light after 5 months without one lol. The denitrator is just a container lined with egg crate and a couple small circulation pumps .... an water input plumbed in from the sump on a small pump that is controlled by my apex to turn it on 3 times a day and flushes the chamber after the cycles. I have an ro line that is plumbed from one of my doser ports that works in sequence with the timing of the beginning of the cycles to feed a 50 50 mix rodi and methonal to feed the bacteria a carbon source.... that's it for the chamber.Thank you! But, I actually would like info on the build for the dentrator. Specifics like how you built it, what are the components... the whole shazam,,, with photos. That sounds so impertinent but I think that the system that you have is simply stunning and the denitrator is a specific that I a very interested in duplicating. There are a ton of denitrators out there but seem to be totally different than your set up. And let's be honest, your results are stellar.
