[Hamza Hamid]

I am loosing my beautiful coraline algae for no reason All parameters in check n good. Mainly calcium is 440.
Every day i find little fell on the sand coming off from the rocks.
Thing I changed as below,
1.Transferred my aquarium from old place to new place. All rocks in aquarium water while transferring
2. Was using Radion XR15 Gen 4 Pro led in old place its damaged in travelling and not working.
Now using Kessil A160WE tuna blue led without controller in constant 75% intensity and 90% blues for 11 hours daily. Corals all look excellent shape only issue with coraline algae. Help me please don't wana lose it.
Please see my tank as below.

Alkalinity swings?

Although most likely light issue. I’d lose most whenever I changed lights. The good news is it will come back.
