coralline algae

[Erak82]

My reef has been up for almost 2 years. All my coralline has faded pretty much. Got my water tested yesterday only thing bad is the kh was high everything else good. My blue leds come on at 9am the whites on at 11am and shut off at 4:30pm then the blues turn off at 8pm. What could be the problem?? Thanks for any hel

Hello I have to ask....are you using RO?DI water? The reason I asked I had FOWLR no RO/DI coralline algae all over! I started my reef build with RO/DI and I have a spot he and there? I run my lights only 8hrs.....
