Glad to help. This is another one I found interesting and the reason I dose much lower levels than most suggestions.

Vitamin "c" dosing Calling the experts...

Another great article. That one is (almost) scientific proof that sodium ascorbate is effective in tissue generation and has a purpose other then a carbon source.
I am begining to thing that smaller doses (below 5 ppm) are just as effective as the 5 ppm in keeping reefs healthy and growing. I am starting to pull way back on my sugar dosing and lower my dose of sodium ascorbate as well. The only real experiment I did with dosing was to stop it for a month. All that did was raise my nitrates way up but coral health didnt change.

Unless you are treated infected corals, I am at the same conclusion. Lower VC will keep tank parameters more stable. By adding another source, such as a small amount of sugar (0.10ppm), you can get the same benefit for cheaper. I've seen a perk in my zoos with as low of a dose as 0.10ppm daily. Currently, I add a total of 1.5ppm total daily and haven't seen much more of a benefit. I believe the further difference that you and Puffer are describing in the RC/Reefs threads is due to the higher doses resulting in nitrate/phosphate depletion.
In the near future, I will be adding VC to my food for feeding time to reduce time/hassle. I will probably add enough to create 0.50ppm on addition.
If you are treating and if you have a dose that works out well for you then I wouldn't necessarily change your regimen.

RBU1, Pufferpunk told you to follow the advice found in that article?
Genetics, I am begining to think that the low dose (maintenance) of vitamin c should be considered to be around 1-2 ppm or lower instead of 5 ppm and people should think about bringing higher dosing levels down when improved coral health and disease have been cured.

Jeff, you're right a lower dose after health has improve may be beneficial longterm. From the last article I posted the author concluded:
Through this research I have determined that dosing 5.28 10-6 moles of Ascorbic Acid per liter daily, improves growth, healing, and health in fragmented soft corals. Dosing at higher amount stunts the growth and healing of the fragmented coral, therefore doses should remain at or smaller than 5.28 10-6 M. Supplementation of Vitamin C can shorten the propagation process making it a more successful option for aquarists and scientists needing to acquire coral.
From a ppm addition standpoint 5.28 x 10^-6M per liter multiplied by 176.12g per M = 9.1 x 10^-4g per liter or better written 0.91mg per liter or <1ppm VC improves growth and healing whereas greater amounts seem to be reversed.

What I don't underastand is in the beginning everyone was using Thiel's math which was wrong and it was much smaller doses and they were seeing results. When they caught the math error they bumped up the amounts dramatically and for what? If you see the results with smaller amounts it just doesn't make sense to me to go as high as some go. Is there something I'm missing?

Thiel was using a different product entirely that was unbuffered and not as potent. His information is 11 years old and is largely untested by hobbyists. People are going higher in their dosing to acieve different results. Some people have cured melting zoas and zoapox with higher doses. That is why they dose at higher amounts.

It's been posted a few times but here you go again:
Use this product:
http://www.iherb.com/ProductDetails...7697039798&at=0
$5 0ff coupon code: LUL789 (good for first purchase).
To figure out how much to use, decide if you want to simply improve coral growth, spread, and color. If so, then you should dose around 5 ppm twice daily. If you are having problems with coral or fish health, dose up to around 30 ppm twice daily.
Calculate the total net number of gallons in your tank (minus rocks, sand, etc). Enter that number here ______.
You will now need to do a little math. The amounts below are for 100 gallons of water so if you have 50 net gallons, cut the amounts shown below in half etc.
Dosing amounts using Iherb product:
1/4 tsp=1112 mg.
For every 100 gallons:
5 ppm ----- 1892 mg VC
10 ppm ---- 3785 mg VC
15 ppm ---- 5677 mg VC
20 ppm ---- 7570 mg VC
25 ppm ---- 9462 mg VC
30 ppm ---- 11355 mg VC
After you have figured out how much you want to dose at each dosing, enter that number here _____. This is your dose to be used twice a day.
Notes:
*Be sure your pH and alk are within normal reef limits before starting. Adjust if needed. Monitor weekly.
*Shoot for a ppm of around 5 if only dosing for improved coral growth, coloration, and spread. Shoot for higher amounts up to 30 ppm if you are having melting zoas or closed zoas and look for the causes of your problems as you dose. Check for high nitrates, pests, zoa pox, predators, and unstable water conditions.
*Dose low amounts and increase the amount slowly over the course of a few days to a couple weeks.
* If you notice an algae bloom or increased skim on your glass then cut back by half until it disappears.
* Watch your skimmer, it will start to skim more.
* Dose the amount twice a day in a fast moving area of your sump or overflow. You may dilute the vitamin c in ro/di water for a minute then pour into my overflow. If adding to sump, try and add the vitamin c after filtration such as skimmers and reactors.
* If you have a question, ask here. I checks this thread daily.
* The instructions in this guide and throughout this thread are based on using pure Sodium Ascorbate, not vitamin c pills and other non-buffered forms of vitamin c.
Be sure to take some "before" pics!
MSHUR, Brightwell has their VC concentrations listed as 1,500 mg/oz. 1oz of VC would be 29.5mL. You have ~50mg VC/mL or 250mg/week VC. 225g tank is ~850L, so you are adding ~0.30ppm weekly.
What is your goal with VC? Are you trying to reduce N/P or trying to get better growth/frag success out of softies? Better coloration in corals?
