LPS corals receding

Reducing your light level is the right step, IMO.
How deep is your sand bed? If cyno keeps coming back, maybe you want to remove some sands, go bare bottom or just keep a very thin layer of it for decorative.

You don't really need to dose all those chemicals. Turn off the light for a few days while cyno is making a come back is better.

Once that's under control, hopefully LPS receding will stop.

My two cents.

I believe my sand was at an inch to 1.5 tops. I have been removing some during water changes.

as for the lights, I did try that for 3 days, but after the water change the cyano came back.

I used to have cyno. Whenever i got it, my sandbed was the first to go. It was only 0.5" deep. Now that I only keep just barely enough to cover the bottom, I no longer get cyno. And I didn't have to dose anything.

Just my experience.
