Vitamin C normally come in two forms
1) Ascorbic Acid
2) Sodium Ascorbate
Normally of the available products uses Ascorbic acid as shown below:
Kent Marine C:
ascorbic acid (vitamin C) in aquaculture grade form of 2-sulfate dipotassium dihydrate
Brightwell Aquatics Vitamarin C:
Ascorbic acid (C) (min): 1,500 mg/oz.
The advantage of Sodium Ascorbate over Ascorbic acid is it have PH of 7.1 as compared with the Ascorbic acid of PH of 2.1. That is why most of the reef forum recommended this vitamin C
If you look at the consideration of available products such as Kent Marine C, you will find this statement:
"Marine•C is buffered but still slightly acidic, therefore it is important that pH and alkalinity be monitored during use of this product."
I have been using Sodium Ascorbate for a month after changing from the LFS available products such as this one shown below:
This is very cost effective.
Just added it to your pellets and add some water to soak the dry pellets before feeding.
