It's been two months, but today, the tank from Advanced Acrylic has finally arrived. Setting everything up will require quite a bit of work, but now most of the components are now in place, I can finally do more serious building.
Here's what I've done in the past two months:
1. Removed the AC vent register for the piping.
2. Finally got the light after a four-month wait.
3. Started acryscaping.
4. Positioned the tank on the stand.
Between the tank and the stand, there's a white HDPE panel. The tank feels quite slippery on it, making it easy to slide around. I'm considering either getting some non-slip material or hoping that the full tank will reduce its slipperiness.
