lighting and clams

[thefishguy]

is two 250watt metal Halide and 2X96 blue atinic 03's enough for clams I have a 70 gallon tank that is 18" deep. I would like to have lights capable of housing any type of coral, clam, fish

Yes that will be plenty! I have successfully kept a clam for a while under PC's. I will be upgrading lights soon though..

[macman7010]

yes that is more than enough lighting for them. clams can be kept in any system with 5-10 watts of lighting with Dersea Clams being the easiest to keep.

With that much light on a 70 gal tank, you can keep just about anything you want.

[thefishguy]

could I get away with 175 watt metal halides and still keep everything

I've seen people use 175's on tanks larger than 75gals, but IMO/IME I would use 250's. This way you'll have plenty of light even towards the bottom of the tank. Also if you get a larger tank later on you would still be able to use the 250's. FWIW, I am very happy I went w/ 250's on my 55gal. SPS's color up and grow very nicely for me and I'm able to keep a Crocea clam happy on the sand bed.
