View Full Version : Corals (LPS, Bubble, Zoas) Freaked Out After Vitamin C Dosing

Hey all,

I know this thread is a bit old but wondering if anyone following before or new might notice and comment on my fresh experience with dosing Vitamin C in a 20 gal Nano. After reading up on all the forums including the R2R 20 page split threads about it, I decided to take the plunge and dose to help with a rapidly melting Zoa colony. I started yesterday with the Brightwell Vitamarin C then switched today to buffered Sodium Ascorbate from iHerb as recommended by everyone in those threads.

What I'm concerned about and wondering if anyone else dosing experienced this is that, within 5 - 10 minutes of dosing, all my corals went nuts! I have two bubble corals that rapidly expanded in crazy shapes (really inflated), then after that they rapidly closed up and pulled everything super tight into their skeletons. I have a branching hammer and a torch coral that retracted and pulled all the polyps inside really fast, and all the zoa colonies glossed over. Even the mushrooms inflated then pulled themselves in.

Here are some pics so you can see the bubbles (lower left) in their skeletons, the hammer and torch (top center) all retracted, etc.

The Vitamin C is all I dosed. They did this just a bit with the Brightwell and now major craziness after the powder. I dosed for 30ppm for a 20 gal tank (putting in about 1500 mg total).

I find it crazy that I experienced this immediately yet no one seems to mention anything like this happening in all the threads and pages and pages of people talking about doing this.

Most say over-dosing is near impossible, and I don't think the dose I described was anywhere near an overdose.

What would cause this and should I be alarmed that everything went crazy and retracted, like REALLY retracted, into itself? We're about 3 hours later and everything is still in hiding.
