I definitely agree with KJoFan. If price were not taken into account I would have definitely gone with the Nanobox quad for my 30 gallon long (and shallow). However, if I had a deeper tank, I would go with something more powerful. Capman- LedZeal also makes a pendant but without the single source of light. I've currently got a kessil A360WE over my 10 gallon and have had die off/ slow growth due to shadowing. Though I do love he shimmer it gives!
