110 gallon tank: dimensions & setup math

48 × 18 × 30 inches (L × W × H). Rounded planning dimensions; measure your tank.

110 nominal gal · about 1,187.99 lb with water, estimated glass and 2-inch gravel.

Estimated working water uses 85% of nominal: 93.5 US gal. The volume tool instead applies 85% to geometric volume. Neither is a measured fill.
