 Re: Building a Denitrator
Just an update. Tank pH is 8.3, effluent is 7.9 running just short of a steady stream through airline tubing. Nitrates are 0. Calcium is 420. The flow is a tad slow and could use a pump as there is a hint of hydrogen sulfate, but as I have the sump heavily aerated with ozone added tot he mix, the hydrogen sulfide is oxidzed before getting into the main tank ( at least the corals and polyps have shown no problems).
My second coil denitrator has way too much backpressure and stops up when an air bubble builds up in the coil, so I will tear it down after Christmas and redesign it.
Cheers,
