I imagine that amount of lighting would cause massive algae growth (not necessarily the desirable kinds), and the fish would probably be scared by it. You would probably need a chiller just to keep the water temperature comfortable for the fish if you don't have one already. I would not recommend it, but I am fairly new to saltwater so don't take my word for it. Do you have corals and/or anemones? If so, what kinds? Are you asking because you are having problems with any of them?

MH over a 16g? Yikes! You're likely to fry the poor fish and corals. Raising the MH lamp so that this won't happen will sort of offset the benefits and simply waste energy. With that said, 80W of PC should be more than ample for Frogspawn (Euphyllia sp.) and Xenia sp.

| Iwasaki sells a line of HQI 70 & 150-watt MH lamps that look like flood lights. I think a 70-watt MH would give you more than enough light alone. I'd recommend the 6.5K lamps which are very white, unlike their 6.5K conventional MH lamps. they require a medium base socket. Word of caution as a sudden increase in lighting can cause problems mentioned above. Andy

| MH on a 16 gal will have your water temp so high it will literally "cook" your inhabitants. HO 50/50 Compacts will provide plenty of light in the correct spectrum and intensity for your tank. Save the MH's for deep tanks (24"+)

Definetely don't get the 150 halides
I would recommend T-5s but I doubt you'll find some small enough, although you can get an 18" one from www.drfostersmith.com they are pretty good I have two of them on my 12
But if you want halide go with the 70 watt halide, 150 will create heat issues most likely.
Second- Your tank is way overstocked, 4 fish?, the 2 clown fish is all that I would recommend
Also it sounds like your current lighting is working so why upgrade?
Just said until you upgrade to a bigger system all together
DO NOT use tap water, make sure you have a RO/DI unit or get it from your lfs, you most likely have metals in your tank that shouldn't be there

OK, first of all, this thread was started back in March. I think Mr Allan has figured out not to use the Halides.
Second, a RO/DI unit is not a necessity. There are places in this country where those metals are not in the water. I have run a reef tank with dechlorinated tap water without a problem at all.
