up...this is a little off topic, but I was wondering what people thought about using the powder to soak food in before feeding fish? Selcon contains "stabilized Vit C" and B12 primarily


I was thinking of soaking food for my anemones in Vit C since they seem to respond well to vit c dosing. I thought this might be a way to avoid upsetting the sps that have closed up on me but still keep those delicious bubble tips going (now if I could only get them to dress up in tiny shorts and a tight tshirt and serve me buffalo wings!)

For those of you having dKH swings or increases... how many of you are using the Calcium Ascorbate?

I know it came up earlier in the thread but it was thought that maybe the "Calcium Carbonate" portion is negligible, but I think it may have more of an affect than we realize. If you look at the content by mass its actually about "9%" Calcium Carbonate--which means that you are essentially also dosing "kalk". So in a 100g tank dosing at 30ppm per day, you are dosing your tank about 2 grams of kalk every day. I wouldn't say thats negligible.

100 tank @ 30ppm. Dosing 11355 mg VC twice a day

11355mg x 0.09 Calcium Carbonate = 1021mg x 2 = 2024mg Calcium Carbonate

Someone please correct me if I'm wrong.
Calcium Ascorbate does not contain calcium carbonate. The most common form is the dihydrate that when dissolved provides 9.39% by weight of ionic calcium. If you are dosing 60 ppm per day of calcium ascorbate then you are increasing your calcium by 5.6 ppm per day which is below the daily consumption of calcium for a tank with low to normal calcification.
Having said that, I consider adding 60 ppm per day of calcium ascorbate to be excessive IMO.

Nevermind I figured it out.

Calcium Ascorbate does contain Calcium Carbonate but not kalkwasser. In the details, it states "Calcium Ascorbate is an optimal nutritional supplement that combines Ascorbic Acid (Vitamin C) with Calcium Carbonate."

http://www.iherb.com/ProductDetails.aspx?c=1&pid=474
That product is calcium ascorbate dihydrate containing about 82% L-ascorbate, 9% calcium and 9% water as dihydrate. No carbonates.

The writing is a bit confusing as it mentions containing calcium carbonate and ascorbic acid. Calcium ascorbate is produced by reacting ascorbic acid with calcium carbonate which results in calcium ascorbate dihydrate plus CO2 plus water. Water and CO2 are driven off and the resulting solid is turned into powder and the powder sold as is or compacted into tablets.

The same phrase you mention can give you a hint to this process but the product neither contains ascorbic acid nor calcium carbonate although it was created by a chemical reaction of both. IMO the phrase is twisting this a bit for marketing purposes to give the impression that it provides two diferent nutrients via two different products in one which in fact does but with a single product, of course if you consider calcium a nutrient.
 
The alk was on a different scale than what is typically used, but I'll look up the figs later. I need to update my info b/c I know have a 30 g. I just started dosing 1/8 tsp 2x a day. Originally, I was dosing 1/4 2x a day.
 
Okay, i just got my Vitamin C in from Iherb.com, the ones listed previously. I want to start dosing 5ppm, i have a 50 gallon tank, so am i right in assuming that should be 2.5 ml? If so, do i measure out 2.5ml of the powder and just mix with RODI and add to a high flow area? Can i mix up a big batch and just add the mixture? I just wanted to make sure.

Cheat sheet:
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


You will want to dose 946 mg of the product asuming you have 50 gallons of water. Each 1/4 tsp of that product contains 1112 mg so to make life easy you will want to dose a little under a quarter tsp twice a day. Start at half a dose and bring it up a little each day until you are dosing just under 1/4 tsp twice a day. I mix it with some tank water in a cup and dump it in my sump after the skimmer.

I dosed ester-C in my old-old-old tank. It was believed to be a cure for ich. (does anyone get this anymore?) It worked fine and the dosing schedule was nearly the same with the ramp up. That was probably 8 years ago. I don't know if ester-C works for these current issues or not, but it seemed to cure my ich.
 
Is running a skimmer a must when dosing. I read all the threads awhile ago but couldn't remember. I've upgraded my sump, but am without a skimmer for a bit. How necessary is it to skim aggressively on VC? Has anyone tried this without using a skimmer?
 
Has anyone had any problems with using the pill form of vitamin C with rose hips.?I was using it and my polyps never looked better.I also have been battling cyano and had 3 fish die.
 
Uded the pill form w/rose hips for 2-3 months. I never had either of those problems. It did eventually lower my pH & alk when I used that. Have you checked those lately? I never had either of those problems. pH & alk are fine, now that I use the pure, buffered form.
 
I'm sorry, I'm sure this is a really basic question -- I just bouught "vitamin C crystals" from TJ's. It says "100% Pure Vitamin C Crystals." And on the ingredients it says 100% vitamin C 'as absorbic acid'. Is this OK to use?

thanks!

It sounds like the exact same thing as I am using. I am using the one recommended by Pufferpunk.
 
Thanks for the updates! I just finished day two using 1/8 teaspoon of the Vitamin C crystals (my rough translation of the amount) for my 30 gallon.

I have two zoa frags that for some reason just don't seem healthy, so I'm hoping this will do the trick. I've always been against putting anything in the water other than my 2-part.

Hoping for good results!
