Advice from your local pool service company
Water balance works as a system
Sanitizer controls microorganisms, pH affects comfort and chemical performance, total alkalinity helps buffer pH, stabilizer protects chlorine from sunlight, and calcium influences scaling or corrosive tendencies. Salt systems add salt and generator-output considerations.
Florida sun, warm water, rain, evaporation, landscaping debris, and long swim seasons can shift demand quickly. A value that was acceptable several days ago may not reflect current conditions after a storm or busy weekend.
Use a reliable test method, follow product labels, and make measured corrections. Never mix incompatible chemicals, and store pool products separately in a dry, ventilated location according to label instructions.

Frequently asked questions
What pool chemistry should I test regularly?
At minimum, sanitizer and pH need frequent review, with alkalinity, stabilizer, calcium, salt, and other values tested as appropriate to the pool and equipment.
Can clear pool water still be unsafe or unbalanced?
Yes. Appearance alone does not confirm adequate sanitizer or balanced water. Testing is necessary.
