The main difference between the fixtures is the way they are built to get the best out of the bulbs.
ATI has the best cooling system there is because it was design to bring out more efficiency in the long run, having the bulbs to last longer. the cooling is directed to a specific spot on the bulbs. That alone is a great feature. It also has splash guard, but you can get one for any fixture, if you need.
But most of the T5 fixtures will work ok over any shallow reef giving out the best light one can wish for any coral.
I've had many T5 fixtures in the past and they all gave good results. Nova, Tek Light, etc..
The ones from Home Depot and
Amazon are made in China and the quality isn't the best!! But they will work!
Many parts of the ATI fixture are also made in China anyways, but they stand behind the German design, inspections and warranties ...
ATI Blue Plus is the best!!!!
Yeah, Tidal Gardens went from LEDs back to the T5s!

Have fun!!
