Something on Euphylia (pics)

[Viperdoug]

For some reason lately my purple hammer has not been opening up fully. Today I noticed a few of the hammers from the tips of the soft tissue are falling off. You can see in the pic below that there is a white ring around some of the polyps (center of pic). Now the two frogspawn are also not opening up very well. Does anyone know what this is, pest or fungus?

I think the pest is in your 3rd picture.

What is your cal, alk and mag at?

I think you nailed it. Alk was low at 6. Calcium is at 440 and mag is at 1400. I started using Alk 8.3 from bright well aquatics last night. I retested this morning and it is at 7. I added some more Alk 8.3. I will check again this afternoon. Hopefully everything is fine.

I have managed to get the Alk. Up to 7.5-8. The corals don't look any different. They opened up a little more today.
