In marine aquariums I'm not exactly new to marine aquariums, but in the winter I started to deal with water quality in order to eventually get the first corals.
Right now the equipment list is as follows:
1. Two flow pumps Jebao mlw 20
2. Jebao AL-90 lights
3. Bubble Magus Curve 3 skimmer.
Also have filter socks, DIY cooler and scrubber, temperature not higher than 27.5 degrees, KH 12.5 (if I understood the Salifert test correctly), nitrate and phosphate in small amounts, almost undetectable by the color of the test, salinity 0.026 +-, red sea salt. RODI water
The problem is that it can several times during the day retract, partially or completely cover the polyps on all or individual branches, as can be seen in the two pictures. This can last from 5 to 20 minutes. At the same time sarcophyton feels its best. Also the third (the bluest) photo shows how it has started to curl up in the evenings in the last few days, but this is probably natural and it just goes to sleep.
Basically it looks healthy, well colored.
As soon as I bought it on one small stone with sarcophyton about a month and a half ago, it began to grow more upward (you can see it in one of the photos right after the purchase), then over time grabbed its foot under the stone and therefore began to grow more horizontally, as I realized.
1. In the first weeks I thought that the reason was the high current, so I reduced it in the day program to 50% maximum in the daytime and placed the left pump higher, as shown in the video. I took the light settings on another forum from a dude, and I lowered them a little on white and blue colors just in case, because I know that in this lamp blue color can burn coral (screenshots of settings also attached), but it all did not help.
2. Then a few weeks ago I thought that maybe it's that the worms (which still build houses out of grains of sand, I do not remember what they are called) with their long white tentacles somehow from time to time disturb the coral and they close for a while, so I began to put cement to cover the crevices in order around there were no worms and no one could not get it. But even this did not help.
In conclusion: it seems to me that this is not normal behavior, but I can't think of anything else. Light, water quality, environment and current should be within normal limits.
The last options could be that it is from below rubbing branches against a rock and it does not like it, or running plankton and somehow it touches it, but in this I have little faith.
Please help and advice
