Does anyone do this? Someone asked me if I dosed vitamin C... and I didn't even know that was a thing. I read a few threads on it from rc and r2r but they are all pretty dated.
I've used Brightwell's Vitamin M (Multi) & C. I add it to frozen food and dripped the C into QT.
It's not something that I've added to the DT other than when it's in the food. I've read it can be good for Zoa's but in QT it's good for boosting the fish's immune system.
I've also read that it can fuel a cyano outbreak...
