Thanks! yeah it's a 90, same footprint as the 55/75 but taller. I really want a 6' someday, but this is my biggest yet, maybe when the kids move out in 15 years haha. I actually went with a commercial aquarium sand and probably overpaid but it was the last step and I wanted my tank running. I used stoney river its actually beach tan but with the led it looks white. I did the black sand for 9 years with my old 60g tank and wanted a fresh start, but loved the black whjle I had it. Planning to try a green terror pair, so may have to rearrange my driftwood to the middle to give each a territory, and add more rocks/wood to make some hidey holes for my pictus cats, but for the first few months the kids enjoy seeing their decorations, then they'll forget and I'll change it.
