Discovering Vitamin C

[urbanfarmer]

Today is the birthday of Albert von Szent-Györgyi de Nagyrápolt (September 16, 1893 – October 22, 1986). Albert was a Hungarian physiologist who won the Nobel Prize in Physiology or Medicine in 1937. He is credited with discovering vitamin C and the components and reactions of the citric acid cycle. It has been over 70 years since his discovery, but his discovery is no less meaningful today.

Don't forget the C also removes chlorine and chloramine. Probably the cheapest way there is.

Yes! However, it doesn't remove some forms of chlorine. Monohalogenated species of chlorine are not affected my ascorbic acid (in other words over 90% of how they add chlorine to water in the USA). Works on all chloramine as far as I know. Please see below:

Nice, do you use powered vitamin C, or citrus? Peppers I hear are very high in C.

I am curious as to how you apply this to the system.

Citric acid and ascorbic acid (vit C) are 2 completely different substances. Citric acid is toxic as certain levels to aquatic organisms whereas ascorbic acid (vitC) is not.

That's why you've heard of people using citric acid as pH down only to have dead fish in a few days blaming it on a pH swing... LOL!

Oops...

1000 mg per 50 gallons to remove chloramine. Some people like to double it to be safe.

Make sure it mixes and aerates well. Dissolve it in a smaller cup before adding it to the larger system.

GOOD LUCK!

I've been using vitamin C for a while now with no ill effects. I also use it to remove chlorine from the tap water for making beer. Do what I did to see if it works for you. Take the required amount of powdered C, mix it in a 5 gallon bucket, and then test for chlorine. If it shows nothing, it is good to go.

It depends what they used to initially chlorinate your water. Again, it's only monohalogenated species of chlorine that don't respond to the ascorbic acid treatment (which is the most common way we do it in the USA, but not the only way). I just wanted to point out that no one should use this method expecting it to have worked and then accidentally kill $3000 koi or some breeders that you just drove 8 hours to get, for example. Of course, testing the chlorine level after is a smart idea for those of us with a test kit!

Ascorbic acid (vit C) has no ill effects on the fish as far as I know and the toxicity reports for it show no response with aquatic organisms, but this is expected given the properties of ascorbic acid... Please don't confuse citric acid (toxicity of 600 ppm for carp) with ascorbic acid (no known toxicity).

If you actually have free chlorine in the water, letting it stand for a few days while bubbling air through it will clean it out. It is removed easily and cheaply by sodium metabisulfite. Free chlorine is being phased out in the USA in favor of chloramines. This is done without any fanfare or public announcement. A product that removes chlorine will not always remove chloramine.

I have used C to remove chlorine from pool water that is chlorinated with chlorine tablets, and my tap water since going to chloramine.

By all means test to see if it works for you. I have yet to find anyone who has tried it and not have it work.
