Another Vinegar question, please advice I have searched:)

FWIW, while that chart was in an article that I co-authored, it wasn't my chart and it has some oddities to it.

IMO, it is unnecessarily slow to ramp up, and the final dose int eh chart is not as related to tank volume as I think it should be. :)
 
Thanks Mr. Holmes-Farley, I will take that into consideration and ramp up a little faster if needed.
As long as you chime in on this tread could I just ask you for your opinion on my starting dose and way of dispensing it, please? And what is your opinion on starting vinegar dosing when KH is approximately 10? Mind you I don't have any SPS, only one Goniopora the rest is softies. I want to lower my nitrates before I add any stonies.

On the forehand thank you for your reply.
 
I think the alkalinity is almost immaterial (within normal ranges of about 7-11 dKH) as long as it is not an SPS tank, or as long as it doesn't become ULNS, even if it is an SPS tank.

I've dosed vodka, vinegar, and vinegar saturated with calcium hydroxide manually once or twice a day, but I presently dose normal vinegar using a BRS 1.1 mL per min dosing pump, spreading the dose out over the daytime hours.

I think a higher starting dose with vinegar is OK because lots of different creatures use acetate and I don't think it will accumulate, even in the absence of bacterial populations to consume it.
 
Paalk I just have to say that you communicate perfectly well for English not being your primary language!!!

+1. If I wanted to post in a Norwegian forum, I'd likely have to use electronic cave drawings to try to communicate.

Who are these people who are gathering in their millions in a frozen midtown Manhattan tonight, sans booze or toilets, to watch a crystal ball descend?
 
Mr. Holmes-Farley, thanks can I ask what ULNS is hehe Vikings don't know all these abbrevations:)

Edinphilly, thank you for that comment I take it as a compliment. Even though we learn English in school over here it is pretty intimidating sometimes to communicate with people who have English as their primary language, especially in forums like this where there is more to the communication than just; Hi my name is PÃ¥l and I am Norwegian hahaha...but after this I will probably start to post more here from now on. Maybe we can talk about coral reefs in the Norwegian sea which was discovered at a depth of 300m here last year hehe

Buzz1329, I would love to see you do that with electronic cave drawings. With our heritage you'll probably be better of communicating with sword and hatchet...sorry not a particularly serious comment hehe
 
I think youir start point is good and safe at 40ml of 7% acetic acid vineagar for a sytem as large as yours.
I would not assume you need to drop the alk. I've been dosing for a little over 5 years with alk at 9.4 for the sps dominant system. PO4 and NO3 are low but not zero as I don't wan't them to be zero. They are: > 0.2ppm NO3 per Salifert test kit ; PO4 readings from .02ppm to .04ppm per hanah colorimeter.

FWIW,my heavily fed 650 gallon system receives 36 ml of 80 proof vodka and 80 ml of 5% acetic acid vinegar daily . That's roughly equivalent to 263ml of 7% acetic acid for 2500liters .

I also prefer to dose kalk and organic carbon separately.
 
Paalk,

ULNS = Ultra Low Nutrient System

p.s. I've worked with and befriended a number of Norwegians over the years. Your written English is amongst the best. There's no need to be shy.
 
Thanks guys for all the answers. I'm sure my nitrates will drop in a few weeks.:)

Rybren, thank you for that. I guess you're in the oil business huh..
 
Hi Paalk! Are you sure that you can only get 7% vinegar in Norway? If you go to Sweden you can get 12% and 20% vinegar in every store. The 12% vinegar it's called "ättikssprit" and the 20% vinegar it's called "ättiksyra".
But I'm pretty sure that you can get exactly the same thing in Norway.

Pks, we even get 35% in ordinary shops here but I thought it was an issue with diluting. I have an impression that when the vinegar is diluted it means shorter shelf life.
 
Why would you like to dilute it? If you use 35% vinegar you would use almost 6 times less vinegar to get the same effect than using 7 % vinegar. Or, almost the same power as using 40% vodka.
Just my thoughts anyway. I'm using a mix of 12% vinegar and sugar and it works pretty well.
//Patrik
 
At 35%, the solution might be a bit dangerous to handle. I'd probably dilute it down a lot, although 12% might be safe enough to handle. I'd have to look over some data sheets to see what I'd do, though.
 
For slow timed dosing larger volumes of solution are easier to manage/dose in some set ups. 5% acetic acid in water is strong enough for good shelf life.
 
I started the dosing on 12.31 with 7% vinegar, filled up a 5l dosing container and it should last for a couple of weeks to begin with. I hope it will start to drop my nitrates in the near future. Thank you guys for all the input you have given me...
 
Any suggestions on how much I should increase the dosage to in week 2 guys? From 40ml to 80-90ml maybe? Appreciate any input...
