Adding t5 bulbs to led lights over existing reef tank

[zheka757]

I'm going hybrid lights method over my established reef tank with mainly lps and sps corals. I'm removing some of my led lights and replacing them with t5 fixtures.
I'm putting a total of 8 bulbs over my 400 gallon tank.

Being that t5 is not dimmable light, how can I safely aclimate my corals to it?
I was thinking only to plug in 2 bulbs at first. Or put the light on 1 hour per day timer. Or just let it all go for 8 hours per day.

I added 4 T5s to my LEDs about 2 years ago. I went with 1 hour/day, and added 1 hour each week. I never messed with the LED spectrum, intensity, or height above the tank. Last summer, at 18 months, I ordered 4 new bulbs. I replaced 1 every 2 weeks. Mixed reef and no issues. The even spread of T5s is really nice.

Thank you for reply, what bulbs you use. Mine came with all actinic bulbs, and I likes how that looks, added 2 coral plus bulbs and it gave a little yellowish look to tank.
I liked all actinic better.

I have 3 Blue+ and 1 Coral+, all 60". These are in a fixture with 3 AI 26s over a 6' tank
