Hi, I have a Red Sea 625 reefer,
I have a mixture of corals, including some sps at the higher light areas of tank, they where going good but in the last around 10 days they have closed up, I haven’t changed anything major, I do regular water changes of around 7% and do maybe 2 a week so average 15%. Only thing that I have changed since noticing this is I have decreased the amount of time between dosing for Kh. I keep my Kh 8-9, and before I would give it a few days and then test, and it might be at 7.8, so I would dose it back up to 9, then give it a few more days and check the drop and dose again. I know that raising it by 1 on a regular basis isn’t the best so I have changed and now dose daily, so a rise of around 0.4 at a time. Any thoughts or opinions on why they are closed? They looked good and had some growth when went into the tank, so I don’t think the lights are too bright. I put Red Sea AB+ in daily, but I don’t feed phyto, just brine shrimp and coral food occasionally,
My nitrate I keep around 8-12, and phosphate at 0.09-0.12 is what it sits at.
