I don't get it, Do you?

I have a 150w metal halide and 100w of VHO. This lighting is on a 24" tall tank. I will be upgrading but something is wrong. My SPS is bleaching when up high near the light(about 6 inches under the surface) but when moved down they start growing again and have full polyp extension.

The water chem is

phosphate 0
nitrite-0
ammonia- is 0
nitrate-pretty much 0
pH is at 8.4
salinity is at 1.025

If you have any ideas on what is going on, please reply.
Thanks Super7

It's too bright. Did you upgrade your lighting all of a sudden? Or has it been like this for a time? Did the corals you purchased come from direct lighting...etc

no i havent upgraded my lighting and the corals came from places with way more lighting than I have.

What kind of reflectors are you using? Could be a hotspot where intense like is focused on a single point.

Try putting the SPS elsewhere near the top.

It could also be the flow in the upper part of your aquarium.

the reflectors are from coralife so they aren't that great, that may be it.
