Ever wonder if Norwesco tank colors mean anything? They do!
Tank color is used to identify the tank grade:
• White (1.5 SG) = Premium Weight
• Light Blue (1.9 SG) = Heavy Duty
• Black or Green (1.1 SG) = Water Storage Only (limits light to help reduce algae growth)
SG (specific gravity) = the weight of a liquid compared to water (water = 1.0).
