AI sol - Hydra?

[JOEYRM7]

I have SOl-blue lights on my tank. I am currently converting over to reef with a tank that is 21" deep. Question # 1 is what is the highest light level I should use withjout fear of burning corals?
#2What is the best ratio between the color light settings?

Is there a big difference to the corals in converting the Sols to Hydras?
Thanks

Power level kinda depends what corals your referring to., for acros you can probably let it fly wide open, stuff like colt corals will seem to melt at same settings. I went from 400 watt radiums to sols a year or 2 ago and didnt have many issues caused by the lights, more temp issues as before going to led I never had use of heaters, now I must have heaters in the winters.
