If it were me I'd try doing 25% intensity for the first week. See how it goes. Then bump it to 50% the second week. You're just going to have to fine tune the color balance to you're liking. But I'd keep everything right at or below 50% for the first couple of weeks at least and go from there. Keep a close eye on everything. Some corals may go through changes, gain color or lose color as they acclimate to the new system or more importantly the shift in spectrum that's been thrown at them. Hopefully this will be minimal in you're case and you will see more growth and more color across the board.
