A couple of updates. I got some nice rock from an LFS that I can use for cave-making. I'll try my luck again.
The bad news is that the tank is running 84f when I checked it today. I was a bit surprised given that the tank is basically open top. Of course, as I'm checking it the heater turns on?! It's set a 78f... So I've dialed it way back to 72f and I'll see if it improves things, otherwise I'll replace it with a better brand like an EboJager or something. The one I have now is a cheapo Aqueon that came with the tank kit.
If push comes to shove, I'll just fire a couple of 80mm fans into the canopy and use them to cool the tank and lights.
