| Price of Pools |
Average | High | Average |
| Estimated Chemical Usage | Surface does not alter water's chemical balance. Substantially fewer chemicals used. | Plaster reacts with water to raise pH levels. Uses substantially more acid & chlorine to counterbalance this chemical reaction. | Surface does not alter waters' chemical balance. Substantially fewer chemicals used. |
| Estimated Electricity Use |
Circulate Water 4-6 hours daily. | Circulate Water 8-10 hours daily. | Surface does not alter waters' chemical balance. Substantially fewer chemicals used. |
| Estimated Chemical Usage | Surface does not alter water's chemical balance. Substantially fewer chemicals used. | Plaster reacts with water to raise pH levels. Uses substantially more acid & chlorine to counterbalance this chemical reaction. | Circulate Water 5-7 hours daily. |
| Surface Texture |
Smooth, non-abrasive to skin or swim suits, walking and seating areas are textured for slip resistance. | Rough, causes skin abrasions to feet, hands and swim wear. | Seams of liner harbor algae. |
| Algae Penetration |
Algae sweeps off with wall brush. | Algae grows and is harbored in pores of gunite. Acid baths and scrubbing required to remove algae. | Surface does not alter waters' chemical balance. Substantially fewer chemicals used. |
| Estimated Maintenance Time | 1/2 hour per week maximum | 4-5 hours per week | 2-3 hours per week |
| Major Renovation | None | Re-marcite or re-plaster at 5-7 years. | Vinyl Liner needs to be replaced every 7- 9 years. |
