Pool water chemistry involves maintaining proper levels of chlorine (1-3ppm based on CYA), pH (7.4-7.6), alkalinity (60-120ppm), and calcium hardness (250-350ppm for plaster). Regular testing with quality kits and proper chemical dosing ensures safe, clear water.
Yes, salt water pools do freeze, but at slightly lower temperatures than fresh water (around 28-32°F vs 32°F). The salt content provides minimal freeze protection, so proper winterization is still essential.
Salt water pools still require chemicals for proper water balance, including pH adjusters, stabilizer, and calcium hardness increasers. The salt chlorine generator only produces chlorine, not other essential chemicals needed for safe swimming water.
Salt water pools are not self-cleaning and require regular maintenance including proper water chemistry balance, algae prevention, and equipment upkeep. The salt water generator only produces chlorine automatically but doesn't eliminate the need for active pool care.
Yes, you can shock your pool two days in a row if your chlorine levels haven't reached the proper shock level or if you're treating algae. However, test your water first to avoid over-chlorination.
Pool cartridge filters typically last 1-4 weeks between cleanings and should be completely replaced every 3-6 months depending on usage, bather load, and maintenance frequency.
Clear cloudy pool water by first testing chemistry levels, then shocking to proper FC/CYA ratio, running filtration 24/7, and using clarifier if needed. Most cases resolve within 24-48 hours with proper chlorine levels.
Pool DE filter grids typically last 1-3 years with proper maintenance, while DE powder needs replacement every 2-4 weeks. Signs of worn grids include shortened cleaning cycles and decreased water clarity.
Cloudy pool water doesn't necessarily mean algae - it can be caused by poor filtration, chemical imbalances, or early algae growth. Proper testing and diagnosis will reveal the true cause.
To raise CYA in your pool, add cyanuric acid (stabilizer) at a rate of 1 pound per 3,000 gallons to increase levels by approximately 30ppm. Add through skimmer or dissolve in bucket first.
Salt water pool systems use electrolysis to convert dissolved salt into chlorine sanitizer. The salt cell generates chlorine from sodium chloride, eliminating the need to manually add chlorine while maintaining proper sanitation.
Used pool filter sand can be used in gardens after thorough cleaning and testing, but it may contain chlorine residue and accumulated contaminants that could affect plant growth.
Pool chlorine can make you sick when levels are too high (causing irritation) or too low (allowing harmful bacteria). Proper chlorine levels of 1-4 ppm based on your CYA level prevent illness.
Yes, pools need CYA (cyanuric acid) to protect chlorine from UV degradation. Target 30-50ppm for regular pools and 70-80ppm for salt water generators.
Cloudy pool water results from poor filtration, chemical imbalance, or contaminants. Fix by testing chemistry, shocking to proper FC/CYA ratio, and running filtration 24/7 until clear.
