ReefKeep66 - I'm in the same boat with this skimmer. I think it's rated for something like 340 gallons (double checked, 317 gallons)? I can't remember, I just know it was WAY overkill haha
djatl - For the Kessil's, i've heard nothing but good things and there is a 30? cube on display at Optimum Aquarium with only a single A350 and everything in there looks amazing. If I remember correctly, it's the owners personal tank? Honestly, I don't care too much about how fast my stuff grows as long as it's growing at a decent rate, and i've heard you can't beat the color or shimmer of Kessil LEDs, which is most important to me. As for the stand, I was in Optimum Aquarium checking out their liverock and the guy that builds the stands they sell just happened to be there dropping some new ones off. I spoke to him and an employee and worked out a slightly custom build (a few accessories) for a stand that basically matched what I was building and it has a canopy as well. I will make sure to take pictures of the kessils inside the canopy once I figure out how to mount them.
I should be wet in the next 10 days or so, so stay tuned.
