Its the phosphates....I am having this exact same issue. Thought it was ALK swings but got that dialed in and consistent but it keeps happening. Did an ICP test and my phosphates were just over 0.5. Working currently to bring this down for good.

I would go with GFO. Just use the recommended dose in a sock. Agitate the sock every second day so it doesnt clump together.
Exchange after 2 weeks. And measure Your phosphate level. Dont go under 0,05 becauase corals need a little phosphate and dont like it if the level is sinking to fast.

Imo low potassium has caused paled corals. What im seeing here is low potassium, calcium and magnesium. If the icp is correct its not surprising they are dying. High po4 wont kill coral ime. It will darken them, and make them not calcify as quickly but wont kill them.
