Personally I wouldn't waste your cash on a marineland led fixture. Cheaply made to say the least. Id go with an AI SOL or even some ecoxotic panorama pro modules would work great in my opinion
Martin @ modularled.ca is a wicked guy to deal with and could give you tons of options on a shallow tank. Great service, free chocolates with any order what more could you ask
lol
Good luck in your hunt for lights
