Today's busy lifestyle makes it difficult for swimming pool and hot tub owners to regularly test water chemistry. This can lead to an imbalance in the water chemistry that can create serious health hazards from bacteria and other organisms in the water. Proper balance of water acidity gives swimming pool and hot tub owners and users a safe bathing environment.

 Balanced water chemistry helps:

• Protects against bacteria and other organisms and reduces skin and eye discomfort
• Reduces corrosion of swimming pool and hot tub unit and fittings, so lowering maintenance costs
• Helps owners maintain correct chlorine/bromine and pH levels, reducing cost of chemicals and risk of chemical over dosing

There is a risk that if the water pH becomes too low it can result in :

• The water can corrode surfaces, metal equipment or fixtures
• The chlorine can dissipate quicker
• The water may cause pitting and etching of plaster surfaces
• Bathers can experience discomfort from burning eyes and itchy skin

 Similarly if the water pH becomes too high it can result in:

• The chlorine sanitation effectiveness will decrease. i.e. the water may have a high chorine level, but it will be less effective in killing the bacteria.
• High pH levels cause calcium and metals in the water to come out of solution, creating the potential for staining and scale formation that causes deposits and discoloration on swimming pool and hot tub walls and equipment.
• High pH can co to contribute to cloudy water
• Bathers can experience discomfort from burning eyes and itchy skin.
