Why It Matters
Water pushes outward equally. Uneven stand = uneven weight distribution at the bottom.
Microcracks form over weeks. Eventually a panel pops at the seam.
Verification
Use a 4-foot bubble level on empty tank top.
Front-to-back AND side-to-side. Adjust shims under stand legs until level.
After Fill
Water weight may settle the floor differently than empty.
Re-check level after 24 hours of fill. Adjust if needed.
Warning Signs
Visible water gap at bottom edge: catastrophic — drain immediately.
Audible creaks from stand: stress — investigate.

- ✦Multiple thin shims beat one thick one
- ✦Re-check level annually
