It’s been running a couple of weeks now, I’ve had to adjust the water flow to keep the ORP in the -100 to -250 range if I let it drop to low you get hydrogen sulphide, had it running at -150mv ish for 8 days now and 1 drop every 2 seconds output and just measured nitrates leaving the reactor and they are at 2ppm salifert, so still not completely converting to nitrogen, but nearly there, all being well another week or so and I’ll be at zero. I can see what I assume is nitrogen forming at the top of the cylinder so I have to vent this. I need to make a small adjustment to the outlet tube so this is pushed out moving forward. I’m not seeing any bacteria coming out of the filter as it’s running now, but if I lower the Orp I get a white snot like substance and can smell hydrogen sulphide but this is not what I want, which may be bacteria but I don’t know, I’m trying to avoid this and create nitrogen gas..
Thanks for sharing!
Would be interesting to know pH, KH and Ca in the outgoing water as well. To see if it's also working a bit like a calcium reactor.
