Well... here's another update. My office decided I needed to be moved to a different directorate and I brought the tank home. It was a huge move and a pain in the rear, but we got it done in about 2 hours (drained, moved to the house). Everything made it... the fish and other live stock remained in a cooler with heaters (it was f*ing heavy) while I reconnected everything and filled the water back to the tank (we salvaged it all sans a few gallons). There are many benefits to this move...
1. The tank is at home.
2. Maintenance is much easier.
3. I get to see it more.
4. I can take pictures!
5. I can do fun internet stuff for it.
My first "upgrade" will be to get everything onto TP Link Kasa Smart Power Strips so I can monitor everything in Home Assistant and control it with my phone and some well placed NFC tags. I'm not there yet, I have some builds to do (slide out shelf, etc) but its going to happen in the next few weeks. Perhaps I'll do a YT video for the journey.
If you aren't familiar with Home Assistant, its basically a smart home controller. I wont spoil all my plans but using the Power Strip lets me do something like this with it... Don't worry, I'm in Japan so that voltage is right and fortunately most everything uses an AC-DC (100-240V) brick now
Tank ****.... this was day 1 after it was all moved.

My GSP rock. Hard to believe this is only 14 months old and its from a GSP rock that jumped over to it. Its well away from everything else now

It started as bare Marco Rock I superglued with sand together
