If it helps, I have an Atlantik Gen 1 V4 and it has been running great, never forgets its settings, and the diodes look great after a few months. The spread has been very good and the PAR seems solid (measured with PAR meter was like 400 in middle and dropped to 200 when at edges of tank). Honestly getting connectivity was a challenge once or twice but overall the app and so on has been great. Keep in mind that the mighty Ecotech reeflink probably goes down as often as the atlantik link (or more).
That being said, my Orphek is over the frag tank and I run T5 +LED bars over the DT and there is an acclimation period for frags when I cut them from the main tank and put them in the frag tank as they get used to the different light. I am not a fan of that phase since I want to sell the frags, not hold onto them for a long time, so I am going back to T5 over the frag tank too (though the Orphek looked sweet). Anyhow. Want to buy an Atlantik V4?
