Observation just before RTN

jjencek · 12/18/2018, 08:08 AM

I have been stressing my acros due to a move to my QT trying to get rid of AEFW.

Two days after the move and a dip in coral Rx, I notice several corrals had "strings" coming out of them. I don't know the name of it, but I thought they were possibly feeding. It was during the light period. Some of the strings were as long as 1 inch.

About an hour later one of the corals with the most "strings" started RTN. It was gone within 4 hours. It was a small colony about 2 inches in diameter.

I did a 50% water change, using my DT water, and the remaining corals calmed down.

Any reason for using CoralRx rather than Bayer?

I am located in Europe and Bayer is prohibited here.

Really not sure what the strings were.. could have been slime, or mesenterial filaments, both would be caused by stress I suppose.
What about melafix? Is that available? Also way less stressful on the corals.

Yes, filaments. That's the word I was looking for. Thank you.

I don't know about melafix. I will look around.
