Need help

[bobthebuilder]

I recently purchased a 15g column fish tank. I plan on growing coral in the future, however i will need a better light for that. Any suggestions on a reasonably priced Light I can get that will be enough to grow low level corals? The dimensions of the tank are around 13x13x20

When in doubt Chinese black box on eBay. Usually less than $100 and will grow anything you want.

Is the 20" the height? If so the Blackbox led is good but will be wider than the tank. They are 8Dxz.5Hx16L. A Kessil or ai prime would fit and do well but not as inexpensive.
