Bleaching corals? Too much light?

[Yinzer]

180 gal. T5 14 39w bulbs. 6 act, 4fiji purple, 2cormax and 2 10k daylight. My sps dieing off, my tan simulates turned bright white (they are on bottom) only 1 type of zoas melting away, I have like 20 different types. I'll post pics in a few minutes. Any ideas? Water quality is fine, salinity was lower than normal though. 1.22

I see that one actinic is out.

This is my tan singular which turned bright white. All 3 did.

These zoas melting but all others ok, I have 3 colonies of these at different levels, even bottom ones bleaching

Both birdsnests turned white.
This seemed to happen after I added the new fijis.

Your salinity is definitly too low it should be around 1.026 also you say your water parameters are fine what are they exactly. You likely bleached the coral when you added the new bulbs.

What is the best way to get them back to normal? Or it is beyond the point of no return?

I plan on rechecking the chemistry again tonight. I'll see if something went out of whack in the past week.
