Cool idea Jim.

Would love to hear your take on the lighting and flow topic? I think that these topics present a a very big challenge for cube keepers.

I choose my cube for some of the exact reasons you mentioned. Large volume, small foot print. I also choose it for its depth for unique aquascaping.

My only regrets with this tank and or suggestions. I wish I went bigger to a 30x30x25, and I suggest taking your time with designing your sump/fug. Limited space under the stand doesn't offer many options. I regret not being able to keep a bigger skimmer.
