Lighting for clams?
Would 2 175 watt MH be ok in a 75gal depth of 20". This would be for a maxima and a derasa. Or should i stick with the single 400watt i have now. The reason i ask is i am building a new hood and have 2 175watt MH and ballasts sitting doing nothing. This would also give me a better spread of light. What do you guys think?
Thanks
Clinton
