that's great, that way i can save money. i went to lfs and they told me that 20w MH would be enough for my anemones. am very confused
I think you are talking about a 20w flourescent. MH's dont come in 20w. Or you got it confused and your LFS said 20k MH, which will be good for your anemones. For the MH lighting it comes in 10k, 14k, and 20k. Me I would go with the MH light from the beginning. I learned a expensive lesson not going with MH first. It toke me 2 flourescent fixtures later to relize that MH's were the best way to go. So from me I would recommend MH's.
20W seems far too low but then again, MH is still different from fluorescent. I'd go with fluorescent rather than metal halides. MHs need to be hang as they tend to give off much heat.
Yes MH's do give of heat but if you have the proper ventalation your tank temp would never fluxuate more then it would normally. I have 2-250w MH's 6" above the water and the highest my temp has got has been around 83 degrees and that right around when I'm going to turn my MH's off, and I have 765w going into a 120gal.
