Today I'm upgrading from PCs to T5s and wonder how I would best acclimate my LPS and anemone to the new lights. At the moment the PCs are 4 x 65w and the T5s will be 4x 54 w with individual reflectors?

Any ideas?

	LPS Large Polyped Stony corals – In the aquarium hobby this is a common division of the species of stony corals based upon the visual assessment of the size of the polyps. Corals in this category were among the first stony corals to be kept successfully in captivity and include many very beautiful species. Commonly kept Genera include Euphyllia (hammer/frogspawn coral), Favia (brain coral), Plerogyra (bubble coral), Lobophyllia (meat/tooth coral), and Caulastrea (candycane coral). LPS corals also include the popular solitary non-colonial stony corals such as Fungia (plate coral), Cynarina (button coral), Trachyphyllia (open brain coral), and Herpolitha (tongue coral). Like their SPS counterparts, LPS corals require good water quality, intense lighting of the appropriate spectrum, adequate water movement and regular supplementation of calcium.

Light Acclimation of corals

thanks chief. Given that the change is not as dramatic as going to Metal Halides, would it be enough to simply reduce the light period?

[Chiefmcfuz]

I would reduce and try to cover the top of the tank with egg crate and slowly remove the screen or egg crate.

[danelam]

sure...where do i get eggcrate from?

[Chiefmcfuz]

Home depot.

just reduce the light period. Don't bother with egg crate. usually people take off one of their window screens and use that =0)

[Chiefmcfuz]

I put the egg crate over the tank and the screen on top of that so it didn't fall in the tank.
