I got your new term right here: http://en.wikipedia.org/wiki/Reproductive_synchrony
And I just don't know if I can ever use PE Mysis again... you've ruined it for me.
It's good to hear everything is doing well. The ironic thing about this is seeing your tank last night after lights out is exactly why I figured a full moon was near. I distinctly recall thinking "Wow, Joe's moonlights are awfully bright tonight." Are all the fish accounted for? You mentioned they seemed to be having a stressful time with the mess.

All the fish are present and accounted for. Thank goodness. The skimmer is still pulling out cream colored gunk (AKA PE).

Definately an exciting but worrisome thing to happen.
I'm glad you were home, and not having someone else looking after your tank, that would have been very stressfull. I can see with the pictures you would have been at it for a while to gets things cleaned up.

Very cool that your tank is going right and the corals are happy enough to attempt to spawn. Sucks that you have to clean it all up and worry about overloading the bioload but cool none the less

I guess you were very lucky to have noticed it.
Do you think this would have still happened without the moonlights? I'm sure the corals will continue to spawn maybe randomly which would be more tolerated by the system. unless if the spawning is also triggered by sensing the PE in the water too.

Did you have the canister filter running as well during the procreation episode?

maroun.c, jnarowe: The actual full moon was the following day but the spawning happened roughly at midnight so I think that qualifies as happening the day of the full moon... or at least close enough. My LED moonlights are on a controller set to the actual lunar solstice so they were at full brightness. I am a believer that the lunar solstice effects coral spawning events and anything we can do to best simulate this contributes to triggering these types of events. In fact, there are also other situations that are regulated by this timing. Ask your wife how the 29.5 day lunar cycle relates to her.
Marc: Spreading that "PE" on anything was not at the top of my list of things to do during this event and the ensuing mad scramble to clear the tank. Besides, who knows what corals may spring up all over my tank now? This wouldn't be the first time. :rolleye1:
matt & pam: If you are referring to my carbon/phosphate canister filter... yes, it was running. I don't utilize the canister particulate filter any longer so no, that wasn't used. Some of my filter socks are 75-micron which is the same as that canister filter. These filter socks did a great job of removing a lot of the creamy muck.

Joseph,
I don't really think the corls can distinguis the difference between DAy 28 and Day 29 as I'm repsuming the light difference is very minimal so you can safely say it did happen at full moon.
I get the feeling that these spawning events are desirable the way you describe them, is that true?
Do you think know you have to check the tank multiple times ever night where it happens to be a full moon. In that case don't yo uthink this justifies a very large mechanical filter that would be run when this happens or maybe from day 25-26 to day 3-4 from the lunar cycle? I would really hate to have this happen while away.
This could also call for a new notification systems that kicks in when water clarity changes for the worst (don't know if such a sensor exists) but seeing that you are very uch invovlved in technology on the tank this could be something to consider.
Very interesting happening indeed.

I always believed that the spawning was about a week before the full moon but I guess that may not be the case. I also don't buy that your lighting intensity had an effect on the corals' but maybe you are proving that to be true.
AND, I thought corals spawned during October or November?

maroun.c, jnarowe: First of all, you may be taking me too literally in regards to spawning events and my tank. I wouldn't state that aquarium reefs directly mimic the ocean reefs. There's simply too many variables coming into play to do so with our closed systems. Keep in mind that I had just done a water change the day of the spawning event. It did, though, happen to coincide with the full moon. I do water changes every month. This happened to coincide with the fool moon. Coincidence? Maybe... maybe not. In fact, on the Great Barrier Reef, spawning takes place six days after the full moon in the month of November. But, it does always takes place at night. The Pacific coral reefs have coral mass spawning that happens a few days after the April full moon. Hmm. (Interesting read.)
So... there was a reason I mentioned in my first post that I had done a water change that day. I'm sure this helped to put into effect the chain of events leading to the coral spawning. Could be chemical, temperature, lighting, gravity or some other (or all) factors. I don't feel that the LED moonlights alone caused this event but I do feel they took part. The fact that they are synchronized to the actual lunar solstice I feel adds to this. But... keep in mind that these are simply my opinions and they are not based on any scientific testing on my part. Maybe I'll setup another 240 without moonlights and compare the two.
Last of all, I'm not too concerned should this type of event happen while I am away. Partly based on the infrequency that this takes place and on the fact that my equipment can handle the removal on a timely basis, on its own. I did take extra steps in an attempt to remove as much "PE" as quickly as possible but I don't feel my system would have any problem doing so on its own. It would simply take longer to do so. Perhaps not the healthiest situation for the tank to have to endure this over a longer period of time but I don't feel it would cause major issues. I am confident in the equipment in place to do this in a fast enough time, though, to prevent severe damage. But again, you have to consider that this isn't happening on a frequent basis. Far from it.

The clams were in fact pumping but whether this was a consumption response or an irritant response, I don't know. I'm sure a very small amount was consumed by other inhabitants but there's no way they were able to even make a small dent in the amount available. I could literally only see about 6" into the tank, if even that far. We're talking dense here.

Definitely more dense than the clam spawn before.
