The Cost of Ineffective Pool Maintenance: The Impact of Total Alkalinity, Calcium Hardness, and pH on Pools
Proper pool maintenance is essential to prevent water from becoming corrosive and damaging pool equipment such as pumps, salt cells (chlorinators), and the pool surface itself. Chemicals like sodium bicarbonate, calcium chloride, and soda ash are crucial in maintaining balanced pool water. The cost of these chemicals is significantly lower than the potential expense of frequent equipment replacement and associated installation costs.
The Role of Pool Chemicals
Sodium Bicarbonate
Purpose: Raises the alkalinity of pool water.
Importance: Low alkalinity can cause pH instability, corrosion, and poor water clarity.
Cost: 4kg = $7, yearly approx. $84
Calcium Chloride
Purpose: Increases calcium hardness.
Importance: Prevents corrosion of pool equipment and surfaces by ensuring adequate calcium ion levels.
Cost: 5kg = $28, yearly approx. $252
Soda Ash
Purpose: Raises the pH level of pool water.
Importance: Low pH (acidic water) can corrode metals and damage pool surfaces, equipment, and plumbing fixtures.
Cost: 1kg = $6, yearly approx. $18 (3kg)
Financial Comparison: Chemical Costs vs. Equipment Replacement
Annual Chemical Costs for an Average Residential Pool:
Calcium Chloride: $252
Sodium Bicarbonate: $84
Soda Ash: $18
Total: $354
Potential Equipment Replacement Costs Due to Corrosive Water:
New Pump: $750
New Salt Cell: $1,000
New Heater: $8,000
Total: $9,750
Maintaining proper water balance with these chemicals can prevent the need for costly replacements of pool equipment, saving thousands of dollars in the long run.
Investing in regular pool maintenance and using the right chemicals to maintain total alkalinity, calcium hardness, and pH levels can significantly reduce the risk of equipment damage and expensive replacements. Maintaining these chemical levels' relatively low annual cost is a smart investment to protect your pool and its components.
By maintaining proper chemical balances in your pool, you can enjoy a well-functioning pool system and avoid the high costs of equipment replacements.
