Dosing regimen for Vitamin C

[Wrench]

Is there a general rule of thumb for dosing Vitamin C? The VitC thread has gotten a little too long and it would take me days to read all 120-something pages. How about a condensed version? I will be using this product, http://www.iherb.com/ProductDetails.aspx?c=1&pid=-7152293197697039798 on a 140g system.

You didnt look very far in that thread for your information. There is an update every few pages but I'll post it again here for you.

Use this product:
http://www.iherb.com/ProductDetails.aspx?c=1&pid=-7152293197697039798
$5 0ff coupon code: LUL789

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
Dose 2x/day.

Be sure your pH and alk are within normal reef limits before starting.
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. I 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 in the origional thread instead of starting a new one. Puffy checks that thread almost daily.

Be sure to take some "before" pics.

Thanks Jeff, you're always on the ball with this!

Thank God for cut/paste.

What's the suggested method for storing the vitamin C once it's opened?

[Pufferpunk]

I put about 1/2 the bottle into a smaller bottle & store in a dark cabinet by my tank & all the rest (I buy 3 bottles at a time) is stored in the refrigerator.

Thank you.
