My tank is 240 gallons 8x2x2. And actually Seaworld is using 400 watt radiums on most of their tanks. I gave them a MX 20,000k to try and am waiting on a report back. Matt I thought about 1,000 watts but I am not sure? Questions on the 1,000 watters: My tank is only 2 feet deep (I think 1,000 watters are too much? How big is the hot spot into the tank? And finally color?
