Corals Shrivelled Up and Spitting Filaments

[downonthereef]

Hello all!

So over the last week, I have noticed, after mid day. My corals seem to shrivel up and start to spit their guts. This started last Thursday, I assumed it was my dwarf angel, being a juvenile and not yet learning his tank manners, but I have since moved him into a quarantine and the issue is still persisting.

It's a new tank, it's been up and running for about 4 weeks, weekly water changes of about 20%, feed AB+ every other day, nothing in the tank only corals, a pom pom crab and a few snails.

Does anybody know what might be happening? I've attached a video. Not very clear due to heavy blues, i'll try and get a better video later. I have not tested the water params (shout at me), but I feel I don't really need to unless something drastic is happening (you may say this is drastic, but too me, it's only after a certain time that it happens, so how can it be the water?) I'm thinking maybe flow or lighting being asin everything seems fine and happy in the mornings.

I have also attached my lighting schedule, this has been used on my tanks for the last 6 months, and everything has been fine until this past week? I will do some tests tonight, though i'm certain the water quality is not an issue.


Thanks, Tiggy

Filament, those squiggly noodle looking things, flow is a Nero3, has random mode on up to a max of 50% goes to 75% over night for an hour or two to pick up the detritus.

When you said noodle, could be poriferan sponge
Will view video in a couple of hours

Can't see squat in all that blue, heck can barely see the corals. Get a better video in white lights and someone maybe able to tell whats going on.
