New Tank 30" tall light?

I have a new tank, it has been many years since I have had a saltwater tank. like 20 years. there were none of the LED and T5 lights back then. what would you all recommend for a 36x30x18 that I may or may not down the road turn into a reef tank? it is acrylic and has a blue acrylic back.

2 of the 120 watt dimmable led lights on eBay will work for reef on your size tank.

Yes there are a large variety. You just need the blue and white panels. Recommend the 30blue/25white panels over the 28/27.

Not to me. The blue and white panels have the blue and white channels on different dimmers so you can adjust the blue/white ratio to fit your tastes.

These will work well for you The 90 degree optics will punch through the water better than the ones with the 120 optics.

Dimmable 120W LED Aquarium Light w 90degree Lens Coral Reef Fish Tank Lighting | eBay

These are even nicer http://www.ebay.com/itm/16-Dimmable-...item4d13970592

I wouldn't use 90 optics on a 18 high tank.

The tank is 30" high and 18 wide.

With just 1 fixture I'd think 120 deg will give better coverage. But if your going with 2 fixtures, I'd agree with the benifits of 90 deg.

The lights i listed will cover a 30x30 area the ends of the tank will be a bit dimmer but it works out well for lower light corals like mushrooms
