How to Lower Chlorine in a Pool. Pool care guide pdf chemistry can be frustrating at times, but high chlorine levels usually have an easy solution.

Indoor pools can be more difficult to manage, but there are still many options available. If you’d like to reduce day-to-day chlorine levels without risking contamination, look into an ultraviolet system. Understand “chlorine smell” and stinging eyes. Many people think that a chemical smell or stinging eyes are signs of chlorine. In fact, these usually show up after chlorine has broken down into other chemicals. Better yet, use a test kit to get an accurate read of the chlorine, as described below.

Use a pool test kit. If you haven’t already, test the chlorine levels using a test kit from a pool supply store. Total chlorine should be no more than 0. 2 ppm higher than FAC. Your local health codes may have different requirements.

If your pool also uses ozone or UV disinfection, FAC can be reduced as low as 0. Just stop adding chlorine to the pool, and the problem will likely solve itself. If you are not sure which system the pool uses, ask the manager or owner. Ultraviolet light from the sun rapidly breaks down chlorine. Ultraviolet lamps are not usually a good replacement for this step.

See the UV method below for more information. Swim while chlorine levels are still at safe levels. Experts disagree on how much chlorine is dangerous to swimmers. Public pools often shut down at 10ppm, while some pools use a 5ppm limit to be extra safe. Do not swim if your pool test had additional unexpected results, such as the wrong pH or alkalinity. This smell is actually from irritating substances called chloramines.

It is more dangerous in poorly ventilated areas, and if the swimmers have breathing problems. Replace some of the pool water. This is an expensive, slow option, but it will dilute the chlorine. After refilling, your pool may take a long time to return to normal chlorine levels and pH. Repeat the pool test once or twice a day, or every couple hours if the pool is still in use. If chlorine levels do not decrease within a couple days, try one of the methods below. See Tips below for guidelines on other test results, such as pH or cyanuric acid.

If your test results fall outside these guidelines and do not correct themselves soon, you may need to hire a professional. Purchase a chlorine neutralizer from a pool supply store. Ask an employee for help if you are not sure what to choose. Do not use chemicals from other sources. The chemicals sold at the pool supply store are at a specific concentration intended for pools. Sodium thiosulfate is probably the most common chlorine neutralizer, but requires care when handling. Hydrogen peroxide is often the cheapest option, and breaks down into harmless substances.

However, this is much less effective if your pool’s pH is below 7. Never add chemicals to a pool while swimmers are using it. If other people have access to the pool, put up clear warning signs. Many pool chemicals can cause injury if they come into contact with lungs, eyes, or skin.

Read the product label carefully for safe handling instructions. Follow all recommendations for safety equipment, and review emergency protocols. Store pool chemicals in a well-ventilated storage area, away from sunlight, heat, and moisture. Do not store acids and chlorine near each other. Do not store dry chemicals next to or underneath liquids. Only have one chemical container open at a time.
