The Science of a Perfect Swim

Maintaining your pool or spa isn't just about adding chlorine; it’s about managing a delicate ecosystem where chemistry meets comfort. Pool and Spa Chemicals are the tools you use to keep water safe, clear, and non-corrosive. When these levels are out of sync, you risk more than just green water—you risk skin irritation, cloudy "milk" water, and expensive damage to your heaters and pumps.

The secret to easy maintenance is the Langelier Saturation Index (LSI) logic: balancing your water so it is neither "hungry" (acidic/corrosive) nor "oversaturated" (scaling). By mastering the basics of Sanitizers, pH Balancers, and Alkalinity, you ensure that your chlorine works at 100% efficiency. Without proper balance, even a pool full of chlorine can still grow algae. This collection provides the professional-grade formulas needed to protect your family’s health and your backyard investment.

Q: In what order should I add my maintenance chemicals?
A: Always start with Alkalinity first, as it acts as a "buffer" for your pH. Once alkalinity is set, adjust your pH Levels, and finally add your Sanitizer or shock.

Q: Why does my pool smell like strong chlorine if the levels are "fine"?
A: That "pool smell" is actually caused by Chloramines (combined chlorine), which form when chlorine is used up. It means you actually need more chlorine or a Pool Shock to break those bonds and refresh the water.

Q: Can I use pool chemicals in my hot tub/spa?
A: Generally, yes, but be cautious of concentration. Spas have much less water and higher temperatures, which causes chemicals like Bromine or chlorine to react faster. Always follow spa-specific dosing on the label.

Q: How often should I test my water chemistry?
A: For active pools, test for Chlorine and pH at least 2–3 times per week. Total Alkalinity and Calcium Hardness should be checked once a week or after heavy rain.

Q: What is the ideal pH range for a swimming pool?
A: You should aim for a pH Level between 7.4 and 7.6. This is the same pH as the human eye, ensuring maximum comfort and preventing equipment corrosion.
