Hydra 64 help

[steeb]

I have 4 hydra 64 I recently acquired after getting back into the hobby.

Par meter arrived late last week and I've been messing with the settings but I think my corals are angry. (also my phosphates are high)

I find the ai app not to be the greatest for scheduling.

My tank is a 96x24x30 and it seems my
Par is about 150 at the top of the rocks. I'm trying to figure out if the 150 par matters if it's more white. I see the brs guide on the hydra 64 but it's for two lights not four.

1 the tank has a euro brace on it and I'm wondering if light can penetrate that
2 should the lights be parallel to the aquarium or turned sideways?
3 Id rather have the blues or moonlight at night but can't seem how to get it right in the app.
The leathers don't seem to be happy. The light intensity was too high. These corals were taken from a buddy a few weeks ago from his year down.

Hi. The light will be reduced by the brace, by how much I don't know.

The light can be straight or slanted, although I suspect some par is lost from slanting the lights but I don't know. 2 of my bars on the outside perimeter of the tank are slanted inwards.

I don't use my moonlight so I can't help with that, sorry.

Leathers are adaptable to high or low light, IME they do better in high light, and they can actually take quite a bit more light than 150 par, so I doubt the light caused any harm. They like flow, and need flow to clean themselves off. This looks to me like a buildup of detritus that blocked that light in that spot. You can try using a turkey baster and blowing on it gently, sometimes I find that perks them up.
