could you add a parts list?
there really isn't much to it. you can see most everything in that first couple photos. one design note that i would add is that the top edges of the stand should be slightly wider and longer (maybe ~1/4") than the aquarium base. while assembling, take care to make sure that the top of the stand is straight and level: i measured from the tops of those vertical 4X4.
i think that the wood is western red cedar. make sure to use cured wood, not the still-green stuff. naturally, the wood is sanded and finished before assembly. i used an oil-based polyurethane as sanding sealer and waterproof finish.
i did find some screws that looked nice with the galvanized connectors. i will try to post a picture of those. the fastener is made by Strong Tie: model #RTC42. i bought them at Home Depot. they also have a similar one that accepts just 2X4's: model #RTC44.
i have a little bit more on my blog:
