Coral Help

[chrisdafish70]

I recently bought 3 frags from an online sale. A Pavona, Lepto, and a Digitata Monti. Recently they seem like they are losing their color. The Digitata has never opened up, the pavona has some white on it now, and the Lepto seems like it is dull. I am not sure what I am doing wrong, I have the lepto is lower light and the other 2 in brighter light and good flow. Maybe it's my light schedule?

My parameters are:
Alk 8.9
Phosphate .05
Mag 1350
Salinity 1.025

I will attach pics and my light schedule. I have an 50gal SCA with 1 16HD Prime and it has been up for almost a year now.

Thank you!

I dont know enough about that light and what you define as "high light", but personally I dont think the pavona or digi should be put in high light at least initially. Both can easily be stressed and die from the shock of high light if they are not used to it with a gradual increase. I would be concerned about too much light for that leptoseris also. I start any of mine basically in the shade maybe 50 par and gradually move to higher light of around 150 par.

Your light is really low. You don't need the green channel, and if you do you can set it very low. But the blues can be up at 100% or above. Here's mine as an example in a 20 gallon.
