I want to venture into SPS and clams and I am wondering if I get the water penetration with the 150 and avoid some of the heat issues if I were to go with the 250.

Thanks for any advice you can offer.

I Have a 30 gallon cube tank running at the moment with a 150 watt Hqi pendant. I have mostly softies but the light output with a 10 k bulb is very nice. I just switched the bulb to a 20K for a little more blue color. If you would like to see some pictures give me your e mail adress and I will send some your way
