NO3:PO4-x conversion to vinegar

I think you'll see a reduction in PO4 in days. Nitrate can take months ,sometimes. I recommend reducing nitrates before starting carbon dosing. Then a miantenace dose keep them low as the bacteria take ammonia without allowing it to produce them.

TMZ, how do you recommend reducing nitrates prior to carbon dosing?
I agree on the skimmer part, that is why I went with a new one.

I have to say, totally anecdotal here, that my system is looking amazing since switching to TMZ's vodka/vinegar mix. Anemones have been very full and my sand seems whiter. I also usually have cyano on my return that sticks the water a tiny bit and its gone

Couple screen shots I just took from my webcams

That return's tip was red up until recently

Rocks, sand, everything looks so much cleaner. It's weird.

I have no idea why I always have cyano on that return but there is a small tiny bit left on it but its turned to white stringy bacteria. Only place I had cyano so never bothered to remove it. Return just turned on so bacteria is floating on the surface which that's always happened. It'll get sucked back down the overflow soon.

This could all be temporary but its very interesting.

I used a diy sulfur denitrator( cost about $100) which knocked them down from the 50ppm plus range to less than 5ppm in two weeks. The system was then 500 gallons which made a large water change undesireable.

Alternatively, I'd remove all detritus possible via siphoning; cut back on feeding a bit for a couple of weeks. When the carbon dose is amped up to about half the maintenance dose , if NO3 is not falling, I'd do some water changes ,say 4 or 5 at 20% over a week to knock them down. By then the organic carbon should be adequate to keep them down. Monitoring NO3 and PO4 along the way.
 
Ok, so for now I'm dosing 5ml of vinegar and 2ml of vodka per your suggestion. I've cut back feeding, and blow as much out of the rocks as possible to get it into my filter socks. I will test NO3 tomorrow and post here to see what you think.
Thanks

Dennis,

Are you still using this stuff? If so, did you get it online or from a local marina?

Thanks

Yup, I am just about to finish off the first 2 L batch of NOPOX I mixed up using it. The jug of stove fuel will last years. I purchased it from a marine supply just south of the QEW in Etobicoke. Unfortunately I can't remember the name of the store. I see that the manufacturer is now selling it on its website. Keep in mind that it is considered a dangerous good for shipping, so it can be hard (and expensive) to ship.

Oh, I just wandered around on Google street view and Klaus Marine is in the right area and looks like the place were I bought it. They had to order it in for me, and I picked it up.

Dennis
 
Thanks Dennis,

The dangerous goods issue had me wondering how you got it. Will have to start making the rounds of the local marinas.

Cheers
 
tmz,
I am up to 4ml vodka and 10ml of vinegar with no signs of bacterial blooms. I'm getting ready to up the dose to 6/15 tomorrow. I'm bumping up 2/5 each week for a month to get to 9/20 as suggested. No real changes in much but I know it's super early in fact it's only 2 weeks into trying it.
I do have my eyes open looking for a DIY suffer denitrator for sale or something.

What's in "artificial vinegar"? Plain white vinegar is just water and 5% acetic acid. It's the acetic acid that's used for the organic carbon source.
 
Interesting I had to look up what is artificial or synthetic vinegar. So, basically if it's not fermented from ethanol or sugar then it can't be called vinegar. If it's derived from petrol it can be called imitation, artificial or synthetic vinegar or just acetic acid.

Then there's food additive 260 which may or may not be from fermented ethanol or sugar.

So, I would check for any additives, flavorings, colorings, etc and it's potency.
 
Thanks for looking it up.

For clarification: I think the author of the linked article uses the term fermentation in a confusing way regarding the ethanol to acetic acid effect .
Sugars ferment to alcohol( ethanol,.eg.) or acids( acetic acid,e.g.) ;the process is anaerobic( in conditions lacking oxygen).
Aceterbacter(sic) ,actuully acetobacter are aerobic ( need oxygen) and oxidize the ethanol to acetic acid.
 
Thanks, I figured it was all oxidation as that's what I normally see when researching the chemistry side of carbon source breakdown. They seemed to be focused more on "eco" friendly so that probably sounds better or more "natural." Don't think they were to concerned about the chemistry aspect of it.
 
You are welcome. Just keeping things in order. I suspect the fermentation of sugars is part of the reason they seem to give corals and anemones trouble vs the relaltively simple path from ethanol to acedic acid and acetate .
