I am in the process of upgrading my lighting with new reflectors and ballasts. I currently have 2 x 175 watt metal halides and I was going to upgrade to 2 x 250 watt. I came across two 400 watt ballasts for free and am considering using those instead. My question is whether this is going to be too much and will it add a significant amount more heat to my tank compared to the 250's. My tank is a standard 90 gallon 48 x 18 x 24. I have anemones and a mix of SPS/LPS but am moving towards mostly SPS. Thanks in advance for any thoughts/input.
