That is kind of iffy. I personally would recommend Metal Halides for clams and anemones. However I have heard of keeping anemones under pc
lights. However they were high wattage systems with several bulbs. Considering you will be waiting till the time is right to add clams and anemones maybe you could save to upgrade you lighting later. Starting with pcs will allow you to keep a nice variety of soft corals, mushrooms, LPS
, zoanthids and polyps. Then when you upgrade to metal halides you can keep clams, anemones, and sps
coral. This is all considering you have excellent water conditions, a mature tank, and have thoroughly researched you new additions. BTW I personally have never seen a clam kept successfully under PC
lighting, but I am sure it has been done. I just dont recommend it. Beleive it or not you probalby can afford metal halides on your budget, I would watch ebay closely. good luck.
