NEW Vodka and Vinegar Dosing Charts

No slime growth or any visible bacteria.
My nitrates are at 70 atm, it's a 50gal tank.

I am studying carbon dosing right now and observed that a sample of my aquarium water when dosed with vinegar shows a reduction in nitrate within 24 hours. I was wondering if you are interested in testing a sample of yours the same way? The procedure is simple. I removed 1 liter of aquarium water and added a scaled down dose of vinegar. I tested the water immediately after dosing and twenty four hours later. I can help you scaling down your current aquarium dose for the sample.

The carbon dosing study is still in progress but thought I would report that a sample of water from my system will consistently reduce NO3 by 3-4 ppm within 24 hours (no further reduction at 48 hours) under aerobic conditions with vinegar dosed at a rate of 1 mL per gallon. These results seem to point to a conclusion that anoxic denitrification is not required to consume nitrate, at least in my aquarium. Thoughts?

I agree with the conclusion, but it doesn't address what happens when other organisms and environments are present.

You can use the higher dose that I posted above and change some water. That will help immensely.

Just make sure your nitrate test is accurate. 70ppm is pretty high. Do you have a lot of fish or feed a lot?

Only 8 small fish in a 50gal tank, i think i feed a little too much. i'm gonna try to slow it down.

Oh I know, I know.

I am working on a two compartment model to see how much we can explain from a simple model of the aquarium.

What do think about inverting a container over a section of the aquarium sand and performing measurements on the trapped microcosm?
