Pool Chemicals for Good Pool Maintenance


Pool Maintenance

A swimming pool is one of the most exciting and enjoyable features a home can have. But when there’s a problem with the water, a pool can become a hassle. Getting the right assortment of pool chemicals in place can help.


Pool Chemical Types

There are numerous types of pool chemicals to help restore your pool’s water to where it needs to be. Pool chlorine, salt, shock and other balancing chemicals might be just what you need to get your pool in shape to swim. There are also specialty chemicals such as algae control, stain and scale control, and pool winterizing chemicals for cold months. 


Water Problems 

When it comes to pool maintenance, there are several different water problems that can occur. Let’s look at the common issues pools have and what chemicals can solve them.

  • For pools with green water, use a chemical designed for algae control and prevention. When algae are allowed to grow, it can cause damage to the pool and requires a more extensive treatment such as a phosphate remover.
  • If your water is cloudy, look for pool shock chemicals. 
  • To clean flakes, scales and stains, use a product labeled for scale, metal and stain control. 
  • For swimmer irritation, utilize a pool water tester, like water testing strips and pool balancing chemicals, to achieve the proper pH balance. If your pool’s pH falls below 7.2, you’ll want to add a pH increaser. If it rises above 7.6, add a pH reducer to help lower the alkalinity of your pool. 
  • For sanitizing the pool, use  chlorine tabletsChlorine is an important chemical in cleaning your pool. Using it properly will allow for a clean pool while also giving swimmers the freedom to enjoy it without the worry of chlorine reactions. If you have a salt pool, you’ll be able to find plenty of chlorine tablets that are compatible.
  • Using a pool filter cleaner will help keep your filter clear of substances that may try to clog your filter. 


Using Pool Chemicals Safely 

As with any cleaning product, you’ll want to make sure you’re taking precautions when administering your pool chemicals. Follow the label’s directions. You may be tempted to add more than you should, especially if your pool is green or cloudy. Pool chemicals are strong, and you typically don’t need to add a large amount at one time. Don’t ever mix chemicals unless specifically told to by the manufacturer’s label. You could make the pool water worse before you make it better. When you’re in the middle of your pool maintenance, never leave pool chemicals unattended where children or pets could encounter them. Always clean up spills quickly, washing affected areas with plenty of water.


Pool Supplies 

Along with the appropriate chemicals, you may choose to get some pool supplies. Whether it’s for in-ground or above-ground pools, see our guide How to Open Your Pool to determine exactly what you’ll need, such as a pool chemical start-up kit. Other pool supplies include pool covers, filters and liners. Pool cleaners such as skimmers, brushes and above-ground pool vacuums help clean dirt and debris from the pool. A pool thermometer will help you gauge the temperature of the water.
