Hi guys need some help. I just added 4 corals 1 zoas, 1 green polyp, 1 plate & a green cloves on sat. The moment i put in it opens up nicely after awhile and also on sun. But today it starts to close up. What is wrong? I did a test reading are pH 8.4, Salinity 1.022, KH 9, nitrite 0, nitrate 5-10, calcium 280-300, po4 0.025.( All api test kit). How do i raise up the calcium lvl? WC or get calcium to dose?
