So I have a set of lobos and favia that are white in spots. I bought and started a new tank recently and transferd fish and corals from a temp tank to the new tank. The only means I had to do this was some Home Depot buckets and a pump to drip acclimate. All fish are fine. About 48 hours late the lobos have turned white on some spots and don’t look as colorful. It’s been 2 weeks. Lobos are no better or no worse. Now I’m starting to see the same with the favia, about 3 days ago. when testing my water phosphates and alk were high. Phosphates are now at 0.10 down from 0.16. Alk due to coral pro salt is staying at 12dkh. I just realized that the last reading I took from the temp tank had the Alk at 8dkh. Is this the likely culprit? Other corals in tank are Xenia, Blastos, Kenya tree, cinnamon rolls, ricordia and all look happy.
