Here's mine... You might have to wait another 6 months for a good growth on my tank :P. Still running the same method (no skimmer, no water changes, my nitrate destroyer, added cryptic zone, live oysters, no chiller).

During the Christmas period, my reef from my mistake , was 18 h without electrical power. Fortunately in the DT I had one RW15 on a diy battery back up, which keep it going for the whole time. All my fish and corals survived. But I had no circulation on my RDSB, refugium , cryptic zone and Don reactor. After 2 weeks I noticed that I have to clean the glass from dusting algae, instead every 2-3 days, every 6-7! I was cleaning the glass so spare, only the first 1-2 months, when I started operate Don's reactor and again now. I attribute that, to the fact that the reactor has an effect on po4 , when the bacteria population inside it, is increasing. When the population is stabilized , no effect on po4, just on no3.

If this is correct, I wonder if we stop dosing carbon in the reactor periodically, so the bacteria population decrease, and then start dosing again to increase it, have a greater effect on po4? What do you think?


PS of course the last few months, I came at the conclusion, that high po4 in a mature reef, are not having any bad effect neither at any of our reef inhapidants nor are promoting algae......

Hey DJ,
Could you elaborate more on the cryptic zone? How does it work and how did you implement it in your system?
Also what do you use live oysters for?

Oh wow, how sad! I used his knowledge and drawings to build and integrate a nitrate destroyer on my new tank. It is working like a charm. He will be missed!!

Does anyone have an update regarding their experiences with the donovan nitrate destroyer. Sorry to hear he passed away..

Final update
I ran my destroyer until mid december 2017 when I took my tank down because I was going to germany for 6 months.
I ran it at 1 ml of NOpOX per 2 hrs (12 ml per day) since from july 15 to december 17th and in that period and my nitrates eventually went to ~ 1 ppm and stayed at that level.

Although this completely controls the nitrates, it did absolutely nothing to control my phosphates. My phosphates were at >1 ppm when I took down my tank,
I pulled apart the destroyer and rinsed out all the pumice when I took it down.
There was a lot of bacterial growth in the first 2/3rd or so of the dual chamber I eventually used for the destroyer.

I attached a photo of the device I ended up settling on for the last 6 months.
I was build by modifying an old DIY calcium reactor.

Thank you for the update! Hopefully more destroyer users will share their updates.

Im interested in building one of these for the sole purpose of providing my tank with bacterioplankton for my filter feeders. At the moment i do not want to lower my nitrate though. Would it be possible to dose the reactor with a carbon and potassium nitrate solution. Is potassium nitrate soluble in vodka, vinegar, vit c etc.? Randy holmes?

Doesn't simply dosing the tank with vinegar at low levels do that.

The reason we all build nitrate destroyers was that dosing even high levels of a carbon source (vinegar , sugar, NOPOX or ethanol) wasn't effectively reducing nitrates.
Our presumption is/was that this was because most of the carbon was being consumed aerobically. So the idea behind the reactors was to more efficiently dose carbon to bacteria in an anerobic environment.

If you want to dose into a reactor for some reason, you could simply make the flow be very very high, in which case, the carbon would be much less efficiently used anerobically and the effect on nitrates should be greatly reduced (i.e. it won't lower nitrates).

My purpose is to generate bacterial feed for filter feeders. I want to grow more bacteria than my tank would naturally produce via low level vinegar dosing which i have tried. I want the nutritional benefits of bacterial reactors such as zeolite and this nitrate destroyer without turning my tank into an ulns

I see what youre saying about increasing the flow to generate aerobic bacteria instead of anaerobic thus reducing the effect on nitrate, but my assumption is i would still be nitrite deficient to generate the bacterial populations i desire. I also dont know which is of better food source but people seem to notice benefit from nitrate reactor effluent and filter feeders so id like to try to replicate that

Pottasium nitrate is soluble to vodka and or vinegar. Have done it, tried to reduce also phosphates with reactor.

Thanks. What ratio potassium nitrate to vodka/vinegar did you use?

I could slso use sodium nitrate if that works better... im not sure what the pros cons are of one over the other

Interesting wonder why no effect on po4. My po4 is ok but i use gfo would be nice to not buy it anymore assuming nitrate is cheaper

Nitrate Destroyer ?...LOL ! you could just as easily put a plenum (Jaubert method)in a separate tank with 4-6" of FCC substrate plumb it inline with your main tank and see ZERO nitrates without having to use additives etc....
