Lighting acclimation question

[LeJeune981]

I have been running a power compact light system. 2 55 watt actinic and 2 55 watt 10k..

I just got an amazing deal on a new/used light fixture

It has 4 65 watt actinic PC lights
and 2 250watt metal halides..

What is the correct way to acclimate everything over to the new lights?

Just running the power compacts. Everything seems happy...

But i just kicked on the 2 metal halides... corals liked it... my LTA and fish... not so much... fish all got spooked and my LTA shrunk to 1/4 of its size...

Needless to say.. the halide on that half of the light is off now.. I'm just running it on the other half of the tank.

I have assorted zoas and pallys.. frogspawn. GSP and xenia. And 2 toadstool leathers...
Scopas tang
2 oce clowns
2 banggai Cardinals
Scooter blenny

LTA and a Rbta (still hidden behind rocks)

It's a 90 gallon reef ready tank

Lights were on a mixed reef 75 gallon tank at my lfs guy's shop

Keep your normal PC schedule and slowly increase the MH I would go for 1 hour the first week 2 the next week so on and so forth up to 6 hours. but monitor the corals if you see any negative then back down by an hour. The fish will get use to whatever the lights are on for.
