Tank is 58 gal 36in long x 18in wide x 22in tall I want to upgrade to MH should i go 2 x 175 watt or 2 x250 watts. Mostly soft and LPS now but want to keep SPS and Clams
If you are planning on upgrading in the future, go 250w. They are the most versatile MH on the market. If you raise the fixture, you'll be able to cover close to 36". Put your softies on the side with the SPS in the middle under the MH.
