That is where he is saying things started to look ugly though. I wasn't sure what was the ml/g he backed up to that seemed to work for him.
I have seen the .5ml/g/day referred to, like TMZ said. I will aim for that to start and see how things look.

I think the number is different for each tank. Some tanks seem to have bacterial blooms with fairly low doses, for example.

I agree the maintenance dose for a specific tank can vary significantly from others given a variety in surface areas ,nutrient inputs /exports and other variables. Amping up to a maintenance dose slowly is recommended . Generally I'd start at .1 ml per gallon and move up to .3 over several weeks and keep it at that level for a month or so before moving up any more if at all , while watching for bacterial blooms and dropping back if necessary.
BTW:This is from Randy's post #31 fyi: OK, I've slowly backed all the way down to about 44 ml per day, spread over the daylight hours. Things look much better. I did not realize how cloudy the water had gotten, presumably with suspended bacteria. That's 44ml for 120 gallons or .366ml per gallon .

I'm currently dosing approx. 25ml of vinegar daily to my 20 gallon tank. Distributed in 5 x 5ml doses.
Which is a lot larger than the .3ml/gal dose and things seem to be pretty stable. No bacterial bloom, no cloudy water, etc. |

Sounds high but each tank differs somewhat. What is the PO4 and NO3 btw?Is iron in range? Any other supplements?

NO3 = 1ppm, PO4 = 0.12ppm. PO4 used to be 0.06 and lower, but then I had the dinos on the sandbed and read about ULNS as a possible cause due to lack of algae and other natural dinos competitors. So I decided to feed a little more to raise nutrients a little. Also introduced copepods. So now I'm trying to keep PO4 at 0.12ppm or a little lower. And see how it goes. |

I am dosing 67 ml/day of a 70/30 vinegar/vodka mix to a 145 gallon system. I think that works out to about 1.43ml/day/gallon.
Last test NO3 1 PO4 .08 I feed a lot and also use an ATS.

No. I don't think I'm underdosing at all whatever chart you are referring to.

I’ve read about your success. I agree that you are dosing what you needed to dose to get your desired outcome. I wish that I knew more details about your success. Not only are all aquara different, they are complex. |

Well, that's a good question. The more popular guess, and I do mean "guess", is that higher alkalinity and very low dissolved nutrient levels might lead to coral problems. There's a lot of hedging there because I don't know of any reasonable theory as to what, if anything, might be happening. It's generally easy to lower the dKH level of a tank, though, and inexpensive, and it seems to have helped for some people, in a repeatable way, so trying it generally seems reasonable.

I now try to keep those levels, except SG 33 ppt, which seems low to me, I'm currently trying to lower it from 35 to 34. |

I dose 1ml vinegar per gallon of tank water per day and feed daily with no issues. NO gha or cyano, and some visible bacterial colonies (both pink and white) Cheers! Mark Update: My DKH is just under 11

The “chart” refers to the one everyone is using, first published years ago, reprinted many times in this forum. If correctly scaled, recommended dosing schedules in this chart would be greater for larger systems. That’s what I meant. Scary large volumes of vinegar are not really “off the chart” :-)
OK The chart was introduced about 9 years ago when carbon dosing began to be more popular. Folks were experiencing bacterial blooms,O2 deprivation and other negatives from rapid and seemingly excessive start up dosing in search of rapid nitrate reduction. The chart provides a very slow safe guide for amping up, but did not provide a cap or guide for maintenance dosing which would vary from tank to tank. The approach then was basically to keep amping up slowly until a rapid decline in nitrate and/or a bacterial bloom occurred and then to back off by half for maintenance. Randy and others wondered how high you could actually go ; hence he authored this thread and his experiment noting 2 ml per gallon led to serious problems in his tank and recovery when he backed off to the .5ml range. I wanted to know what others were experiencing ,so I started a thread on another forum . From contributions to that thread , reading a hundred or more anecdotal accounts over the years , Randy's work and about 10 years of dosing I've settled on recommending .3 to .6 ml of 5% acetic acid vinegar or equivalent amount of including 40% ethanol vodka(80 proof) per gallon as a reasonable normative max cap range with tweaks up or down based on observations of a particular tank . In my case 36ml of 80 proof vodka; equivalent to 288ml of vodka plus 60 ml of 5% acetic acid vinegar dosed daily to the 700 gallon system for many years maintains low nitrate and PO4 without toublesome conglomerations of bacterial mass or blooms and a minimal .15 or so decline in pH which is offset by kalk dosing and a CO2 scrubber.
