Just picked one up to try out on my 30 gallon cube I just set up..... Currently have a Kessil A150 sky blue but didn't like the fact that it was just on/off.... Then trying to figure out a moonlight was proving to be a challenge since it's an open top tank. So my LFS was having a store wide 20% off sale so I figured why not... I Like the fact it has a built in controller, customizable settings ,adjustable tank mounting bracket and super slim design. LFS was also having a 30% on all livestock so picked up a couple naked ocellaris clowns and a green bubble tip anemone... Bta is about 20" directly below the light so curious as to long term health under this light.
