Don't feel bad I took out my T5HO and VHO and I just have 2-250w/1-175w MH on my 200 gal and the same combination on my 158 gal. The 175w's(one on each tank) run on two of the old coral life solar systems that where famous in the late 90's with dimming ballast that take two hours to get to full brightness and 2 hours to dim down to full darkness. Curious to see how long they last. The funny thing is when you take a picture they look bluer than in real life?
