Correct Pool Settings Guide for Astral Pool Salt Chlorinators

To ensure your pool stays clean, safe, and comfortable, maintaining the correct chemical balance is essential. Here’s a guide for ideal water parameters and adjustments to help you achieve perfect balance, with a focus on Astral Pool salt chlorinator systems.

Guidelines for Adjustments

• Free Chlorine: To raise chlorine levels, add chlorine directly or adjust your equipment’s output.
• pH: Increase pH by adding buffer or soda ash; reduce pH with muriatic acid for proper balance.
• Total Alkalinity: Use sodium bicarbonate to raise alkalinity or muriatic/dry acid to lower it.
• Calcium Hardness: Adjust by adding calcium chloride, or reduce by partially draining and refilling the pool if levels are too high.
• Cyanuric Acid: Increase with cyanuric acid and decrease by partially draining and refilling.
• Salt Level: Check monthly. Add salt as needed, or drain and refill if levels are high.

Regular monitoring and adjustment following this table will keep your pool within optimal parameters, enhancing the effectiveness of your Astral Pool salt chlorinator for a clean, comfortable swimming environment.

Maintenance Guide

For regions with high calcium hardness, periodic cleaning of the electrode is recommended to ensure optimal performance. Use a Salt Chlorinator Cell Cleaner or a 1:10 solution of hydrochloric acid to water, and always follow local disposal guidelines for the cleaning solution to protect the environment.
