To much flow for SPS symptoms

[chercm]

Not sure if it's just the pics but some of the corals looks like it has burnt tips. possible alk issue or they're getting blasted with too much light?

too much light ??? I am using AI hydra 52 LED , what is the light hours that is not considered blasting too much light ?

Ok I want to address the new frags and old colonies now having issues. While I agree alk swings can burn it looks like patches are being eaten. Have you dipped again with a magnify glass some of the new frags for pests? Just want to rule them out.
