Hey Beetle - thought I lost ya! welcome back to nitrate city
Well, your post prompted me to test the effluent which I haven't bothered doing in a long time. While I'm waiting for the results, I'll recap.
To make 'good' water for water changes, 1) I setup a 10g in the garage to filter water using the Fluval Lab Series Nitrate Remover. This gets my off the chart well water down to 5ppm nitrates; abd 2) I also make deionized water using the API Tap Water filter. The DI water requires minerals and pH balance so I'm using Seachem Replenish and Neutral/Alkaline Regulators. I mix these 50/50 to do a 10g weekly water change on my 60g tank.
In order to facilitate the reduced volume water changes (which have been in effect for 3 months now) I am periodically using activated carbon and Seachem Purigen. I also have a pouch of API Nitra-Zorb in there from time to time to keep nitrates at bay. To ensure ample trace elements, I'm adding Seachem Fresh Trace with each water change and am [still] using Prime here and there.
Okay, the timer rang and the effluent test is in and it's 10-20ppm, so there is little indication that the bio denitrate filter is handling nitrates. <colorful adjectives go here!> I believe it's handling ammonia and nitrites...but anaerobic bacteria are being stubborn.
I'm going to cut the flow back to mere drips and see what happens in time.
So I haven't given up, but this is far from the slam dunk I hoped it would be.
