New to this forum,so I thought I'd give it a try.
I'm getting ready to replace my MH bulbs. I noticed that the stock bulbs that came with the fixture were 150 watt-10000K. Can I upgrade to 250 watt-10000K, in this fixture or will I need to get a different ballast. My tank is 32 inches deep so I thought increasing wattage might be beneficial. Thanks
