Thank you for your comments and suggestions.
I did a water change the day after it first started. I also changed out the carbon the same day. I run an Ehiem canister filter full of marineland black diamond carbon for my carbon filtration.
I will do another water change today. My tank is set up to do max water changes of about 40 gallons or 15% at a time.
I've thought there must have been a quick water parameter change or something as well. I tested all water parameters on the Thursday before it started happening and then tested everything again on the Tuesday that I noticed it. The only difference was the calcium was a tad higher but that could have been the result of reading the test differently. I use salifert tests. I also can't imagine that a slight increase in Calcium would do this. Perhaps something happened inbetween Thursday and Tuesday that I am unaware of.
What parameters specifically would be most likely to effect Florida ricordea?
I agree they are incredibly hardy! These have been in my tank for over two years and have grown from 10 polyps to 60+ (and now back down again). The part that I don't understand about the water parameter part is that it would seem like some of the other more sensitive corals in my tank would be showing some distress as well...especially if it was so bad as to effect the rics! Does that make sense?
Also, the only ones affected seem to be the ones that touch the ones or one going bad at the time so something is definitely spreading.
Chillman,
The only thing I added were the two rics that are on top of the second picture. I moved them and placed them on top of the rock that had all of these rics on it. They probably did touch and that is where the problem started. Hmmmmmm. Could they have had some kind of dormant funk that they could fight off but this other colony could not? Is that possible? Those two are still fine.
Sugartooth,
Thanks but not possible to dip them. They are on a rock at the bottom of the pile
That's why I tried to squirt vitamins at them! LOL
2 more gone today....
