AI Prime 16 HD

[The Fish Tankist]

I am upgrading my 5 gallon tank to a 20 gallon Nuvo tank. I am looking to be able to house any coral from softies to high-light sps and clams. I currently have a kessil A80 but I think I need to lights on the tank. I was thinking about adding a Prime 16HD with the kessil and then getting another 16HD in the future. Does this sound like a good plan? Does anoyone have a 16HD they would be willing to sell for a decent price?

Thanks
