20 Inch 2x18 Watt AquaticLife T5 HO Light Link Fixture is going to be inadequate for anything but a fish only tank. Lowest light 10 gallon tank I've run had 2X26 watt curly PCs and I only had mushroom corals in the tank, and even that was marginal.
No offense, but that's not true depending on the brand and out put. I ran 2x 18 watt nova on my 10 gallon, and had great results from it. I kepy all softies and a couple LPS. Everything did great. I don't think I would try any high light demanding SPS though.
