Most other brands are at 4% and for the life of me i cant find distilled anywhere except online where they want my first bourn and my kidney.
That's probably fine to use.The only Vinegar in the state at 5% Acidity is Anchor white vinegar fermented.

I recommend distilled while vinegar. This one is filtered, not distilled. That may or may not be the reason you detect a skimmer change, but it is easy enough to try distilled white vinegar.
White vs distilled vinegar - Sweet Living Magazine
White and distilled are types of vinegar. They differ fundamentally in their acetic acid content. So which one should you use for what?www.sweetlivingmagazine.co.nz
Most people agree that the basic difference would be the level of purity. Simply put, distilled vinegar has been purified more than white vinegar.
The problem is that distilled white vinegar is not readily available in Australia.
good day, I will start dosing vodka for my 45 gallon acro tank. My nitrate is 15-20, my phosphate is 0.05, I use rowaphos in the reactor.
Hello,I have a silly question: Should I dose daily or once a week? Thanks!The reasons I'm updating the Vinegar and Vodka dosing charts are two-fold:
1. The ramp was unnecessarily slow. There was no perceived benefit to such a tedious ramp, and it led to reefers quitting because they thought carbon dosing didn't work.
2. The ramp did not scale up correctly at all. A 40x larger tank only received 2x the needed dose. (A 1,000-gallon tank only received twice the dose of a 25-gallon tank).
Carbon dosing is a fantastic way to lower nutrients, more specifically nitrate. The reason is three-fold:
1. Organisms, such as bacteria, contain much more nitrogen than phosphorous.
2. Denitrification is a process that happens in anaerobic conditions (little to no oxygen). These bacteria require an organic to oxidize the nitrate molecule (NO3-) into Nitrogen (N2). They use the oxygen that is attached to the nitrate molecule to respire. Thus, there will be NO phosphate consumed during this process.
Here is the equation by @Randy Holmes-Farley :
organic + 124 NO3– + 124 H+ → 122 CO2 + 70 N2 + 208 H2O
3.We have an immense reservoir of phosphate bound to calcium carbonate rocks and sand. To put to pespective, a 50% water change with nutrient-free water will successfully reduce your nitrate values by 50%. More often than not, the phosphate value will climb right back up near the starting point after a day; PO4 tries to be in constant equilibrium with the bulk water column and calcium carbonate surfaces.
For these reasons, I do NOT recommend dosing carbon solely for controlling phosphates. It is likey to deplete nitrate before seeing phosphate mildly decrease.
What are the benefits of carbon dosing?
Besides reducing nitrate, spurring bacteria is the main benefit. This bacteria can feed many organisms and filter feeds (such as desirable sponges) in a tank. Coals and sponges can directly metabolize acetate. Acetate is one of the highest turnover organic in the ocean. Thus, opting for vinegar can be very natural and is something out tank inhabitants are accustomed to.
What about other carbon sources such as NP Bacto Balance, NOPOX, or Sugar?
You can carbon dose with NP Bacto Balance or NOPOX, but dosing straight vinegar or vodka is cheaper and readily available in stores.
One caveat is dosing sugar. While it was popular to dose sugar in a tank several decades ago, it has largely fallen out of favor. It tends to "brown out" certain corals. I wouldn't consider dosing sugar.
Vodka (80 proof) is eight times more concentrated than 5% Vinegar. Dosing 8 times less vodka than vinegar will equal the pH lowering effect and nitrate reduction.
What kind of vinegar or vodka should I use?
Plain Distilled vinegar (5% acidity) from the grocery store is best. NOT filtered vinegar.
Unflavored 80 proof vodka (40% ethanol) is best.
Instructions and rules to follow when carbon dosing with my charts:
1. Dose during daylight hours. Carbon dosing will reduce pH and oxygen, so it's wise to dose while those parameters are naturally at their highest.
2. Skimming and good surface agitation is strongly encouraged. If you don't have a skimmer, stay on the lower end of the chart, and don't progress unless it's clear the tank is fine. High flow will allow more oxygen in the tank and will gas off the extra CO2 that gets produced.
3. You can dose vodka in one shot (bolus dosing), but vinegar is best spread-out with a dosing pump or manually twice a day.
4. Vinegar and Vodka have the same pH-lowering effect, but vinegar is more upfront, while vodka is all later as it becomes consumed by bacteria. You cannot easily detect the pH drop from vodka, but they are equal when comparing the chart dosages for tank size.
5. You do not need to increase the dose after week 2 if nitrates are reducing earlier.
6. Watch your tank and make observations. Once your nutrients are in line, find a small maintenance dose for your tank. You choose the final dose based on your testing and tank inhabitants.
7. Keep track of nutrients and ensure they don't bottom out. Nitrates won't bottom overnight; you won't wake up on the second day and see 100 ppm turn to 0.00 ppm. It's much more gradual than that.
8. Some people notice cyano issues with vodka than with vinegar. If that is the case, switching to vinegar is a wise choice.
Here are the charts. If you have any questions, feel free to ask.

Randy actually didn’t make the chart. He thinks the ramp is unnecessarily long, too:
Post in thread 'Vinegar and Rox Carbon?'
If the week one dose is too strong, I’d reduce it by 50%. If it’s still lowering N too much, reduce it further by 50%, etc. It’s all about trial and error.
I still grow algae on my glass just fine. I highly doubt there’s going to be anything wrong with less algae on the glass.
Here's a typical paper that shows corals can take up acetate:
Lipogenesis in the intact coral Pocillopora capitata and its isolated zooxanthellae: Evidence for a light-driven carbon cycle between symbiont and host - Marine Biology
Surface tissue of the reef coral Pocillopora capitata contained approximately 34% lipid on a dry weight basis. Of this, 75% was storage lipid (wax ester and triglyceride) and 25% structural (phospholipid, galactolipid, etc.). Based on chlorophyll a: lipid ratios of intact coral and isolated...link.springer.com
"Coral tips and isolated zooxanthellae were incubated with sodium acetate-1-14C in light and dark to obtain lipogenic rates and proportions of fatty acids and lipid classes synthesized. The rate of lipid synthesis from acetate-1-14C by intact coral was stimulated three-fold in the light (1200 lux), which indicated that the majority of coral lipogenesis occurred in the zooxanthellae. Intact coral triglycerides contained ca. 68% of the 14C-activity and wax esters ca. 21%."
Yes, text works out just fine. It’s just things like pdf, jpeg, charts and graphs. I had noted Randy’s comments regarding the long ramp up and volumes within this thread. I like to try and read a bit on topics that I find interesting from time to time. I am looking at the other threads linked now. Thanks again! I had cut the dose by 20% as the decline in n was not drastic by any means. Not enough time has elapsed to determine if that is sufficient.
