So I bought fruit loop zoas and got them from tidal gardens last Saturday. I dipped them in coralRx and then bayer. Later on in the night they opened a little. And for the first 2 or 3 days they only opened a little. But a few of the heads never opened full and looked irritated by some hair algae that came on the plug. So I dipped it in 3% peroxide for 5 mins. And it has not opened since. I am attaching the before and after peroxide pics.
