Very exciting. One piece of advice I would have for you so to consider some sort of leak detection system. One of the things I regretted about my 535g tank was placing some sort of trays to capture water underneath the tank. For example, my tank was sitting on a bamboo wood floor. Unfortunately, there was a tiny leak on my piping from the reeflo pump to the ultima. The water pooled without me noticing for a bit and now I can see the floor damaged all over there. My solution was very simple. I went an bought some large black dog crate trays on Chewy.com and just placed them under my stand. I then was able to place water sensors inside the tray.
Be careful around those closed bulkheads low on the tank. I hit a bottom drain 1/4 bulkhead that I had in my tank, and it started leaking. I was forced to take the tank down until I could seal all bottom holes. I have had too many water damage issues in my house the past couples years that has made me much more conservative about extra protection.
