With PCs there is no acclimation for corals needed. Algae will immidiately adapt to any new lighting. If algae is your concern, then sticking with the original NO Lights will be a lot better than the PCs. But as for coral growth, going with the PCs is a better choice. To keep algae at bay, though, you will need to make sure that the bulbs are replaced often. Once every 6 months I believe, but it varies on the type of bulb (IE MH, PC, VHO, T5, etc). To help deter algae growth, lower degree bulbs help keep algae from growing but won't stop it. 20,000K bulbs for example produce less amount of needed light. 5500K-7200K produce some of the best light for algae.
