Ai hydra led 400$ controller is a bill but its more then worth it real time weather sims just pick a region and all colors fully adjustable can set % for lightning storms and cloud cover our if you weather sim when there is a storm in in Fiji there's a storm overt your tank =). Radion led will simulate water conditions as well but at a much larger price tag as you need the power heads to go with it.
. One of my friends loves the hydras, so I was really leaning towards the 26, and the radions are currently in second place
Want to see how they do on the nano, before I even think about getting rid of my halides on my 150 reef.
Don't forget to check out the Kessil's. I had Vega's on my last tank anc could never get them dialed in correctly. I put the A360ew's on my new tank and am loving them. Everything in the tank is responding great to them.
