The Puffer Forum

I've been researching (reading 100+ page threads) of vitamin C dosing to improve overall health of fish, zoa's, etc. as well as polishing the water chemistry a bit more. All of the threads recommend a supplement purchased from iherb.com. The links, however, are outdated and dead-ending for me.

Can anyone provide the actual brand name of the vitamin C that is being used? If not, looking on Amazon, they have a few brands...would these work?
