Lighting for Xenia and Purple Digitata

[dan83]

I will be receiving two new corals this week, a xenia and a purple digitata. I am also about to install a VHO lighting system which will consist of two 24" 75watt bulbs, so it will be 150watts, or about 5 watts/gallon. My tank is a 37 gallon, and has been running for about two years now. I have about 10-20lbs live rock. current inhabitants are a small (2 inch) pair of cinnamon clowns, about 15 small to medium brown/green mushrooms, some small (1 inch diameter) anemones, which are spreading quickly, a small conch, about 30 astrea snails, a large serpent starfish, and some other snails. I have sawblade caluerpa growing in the tank and harvest it regularly, and with the other filtration systems the ammonia and nitrates are always at 0. water movement is about medium i would say. Do you think the new corals will thrive in this setup? what additives , ie calcium, should I start adding to the tank?
should i be measuring other factors besides ammonia and nitrates? I also have a ton of small red/black bristle worms, but they have never harmed anything. also, i have read about others having this type in reef tanks with no problem.
what do you all think?

I hope that those little anemones are not aipstasia or majanoes, because they become a real big pest in a short amount of time. The aipstasia look like little anemones and are a slight pinkish tone. Just google aipastia to find a better discribtion or picture. You may want to consider getting rid of those.

i do plan on keeping the anemones under control, i think they are one of the types you mentioned. i am going to move the rocks around so that they are far from the corals, and will keeping an eye on them spreading in that direction.
no advice on lights? people seem to jump on this all the time....
