I have one too. It drools during the nite when my lights is on Moonlight. During the day it opens and expands pretty well. I think it is more of the current that this tree corals need. Well I have a Maxspect Gyre XF130 at 50%, blowing at them at 2.5 feet away.

Case solved now after simple advice from Bellinayu to adjust air valve. How stupid of me not to try that. But earlier I did but maybe the SG was too low. Now at 1.022, the adjustment of air valve works. Thanking guys and gals for your fast and kind advice.

Update my SG is 1.022 but the cup still has lots of overflow of bubbles. Do u think it might be the case of using NSW.

Yes so far it is recorded as 1.023 but Bellinyu my friend has ever used a refractor to measure against my hydrometer. And it is 2 points out. Meaning it is now at 1.021 will try to increase further to 1.025 thanks for all advice.

Thanks ASHWIN will pre mix a very concentrated one to add into the tank. I have purchased a RODI unit from madpetz so that new top up would be better.

Hmm... When I first got the NSW, the SG is 1.017, now I am adding more salt (Coral Pro) to increase the salinity.
So far it is reading at 1.019.
Should I dump in more lots more salt so I can achieve like 1.023?
