Ulva on frag

[Cherie cook]

So…treating ulva on a prized frag…peroxide with a q tip or just scrape it off? Don’t want to damage the frag, obviously.

Just scrape off out of the tank, then apply a little h2o2 to the area where the ulva was, let sit a minute and then rinse in old tank water. Watch for new growth, as ulva can be a tough one. Most crabs, snails and herbivores will eat it though, especially new growth.

Edit: depending on the coral, you can also remove it from the frag plug and place on a new one. Then let old dry out, rinse in h2o2 and use later down the road
