Well been debating over the ATI and Tek for a while now. The biggest difference I see is the price. Have not seen many tanks though with the ATI over a 20L. Not worried with either choice because surely each will have it's own advantages and disadvantages.

The price range is not too big of a deal at the moment as I have just been looking at different lighting since I purchased my tank. Reading everything I can about how each light works and the benefits each offer. Thanks again and hopefully will get this thing up and running shortly.

Thanks,
Marc
