  • Bubble Polyps ready for Bail!

    I remember a while back we had some discussions over SPS corals that would show a bubble instead of a polyp. I for sure thought it was some type of water parameter that was out of proportion to NSW levels. Mainly Mg. I had this problem and so did others. It went away after a while.

    But today, I found an article that brings us closer to our experience:

    Paul Sammarco and Robert Richmond discovered that polyps, even after secreting a calcareous skeleton can "bail out," and swim into the water. This can occur, for example, just after a planula larva has settled, metamorphosed, and secreted a skeleton. The bail out occurs in response to poor conditions, such as poorly oxygenated water.


    Called "Polyp Bailout"

    Edward, polyp-bail-out & air-bubbles at the tips are two different processes. Possibly after p-b-o, an air-bubbles ocurs Bob

      Looks to me as if they are the same.. the polyp inflates and releases into the water.

        Edward I actually had that problem about a week and a half ago on my montipora, and stumbled across a thread that you posted on about low Mg, but no one wanted to listen to you. When I checked my Mg levels they were at 990!!! It has gone away since raising. I believe you had it pinned down

          I had my bubble polyp problem for the longest time a while back thinking that my Kent salt provided the Mg my corals needed. After ordering a test kit, boy was I wrong. As stated above, its definitely due to "poor conditions". Glad you found your problem! Give it some time and you will see your corals healthen up!
