Our Favorite Pool Chemicals and Water Testing Supplies

It’s hard to practice good pool maintenance if you don’t have the tools to accomplish it. Stock up on a few essentials, and then build from there. There’s no point in owning a pool if it’s all drudgery. Having the right tools at hand will make your life a lot easier, and allow you to enjoy your pool much more.

Pool Water Testing

We cannot stress how incredibly important water testing is for your pool maintenance. It’s best to test your water at least once a week. Regular testing lets you know when you need to add chemicals to your pool to prevent nasty bacteria and algae from moving in.

Our Top Pick
Complete Liquid Test Kit for Pools and Hot Tubs

A simple but effective liquid test kit for chlorine pools and hot tubs.

Tests for 7 important chemistries in seconds: Total Hardness, Total Chlorine, Total Bromine, Free Chlorine, pH, Total Alkalinity, and Cyanuric Acid.

Instead, stock up on test strips. They’re not quite as accurate as liquid test kits, but they’re quick and easy to use, and cover all the basic levels you need to keep track of free chlorine, total chlorine, bromine (if you use that instead of chlorine), total hardness, total alkalinity, pH and cyanuric acid.

Pool Water Balancing

You need to balance your pool water by maintaining the proper pH, Alkalinity, and Calcium Hardness Levels. There are four different chemicals you need to help balance the water.

For increasing your alkalinity, you can either use our favorite Alkalinity Increaser or baking soda.

Our Top Pick
Pool Alkalinity Increaser

Perfect for raising total alkalinity and pH in your pool.

NOTE: if you want to lower your alkalinity, you can use muriatic acid.

For controlling your pool pH balance, you can use pH Increaser and pH Decreaser.

Our Top Pick
pH Decreaser for Pools

Use this chemical to lower just the pH level in your pool water.

Our Top Pick
Soda Ash

This is the main chemical used to increase your pool's pH. So instead of using a branded version of pH Increaser, you can just use soda ash.

Our Top Pick
pH Increaser for Pools

This is a proven way to make the water less acidic when swimming in pools. This chemical helps maintain the right level of pH.

And finally, you need to control your calcium hardness level if you have an inground swimming pool. You can use calcium hardness increaser and it’s something you’ll only use about once per year. If you have a quick set-up pool (Intex), then you don’t need calcium hardness. Calcium hardness helps prolong the life of your pool lining whether it’s concrete, fiberglass, or vinyl.

Our Top Pick
Calcium Hardness Increaser for Pools

Adding calcium hardness to your pool water will protect and extend the life of your pool walls including vinyl, fiberglass, and concrete.

Pool Sanitizer

Our favorite sanitizer for a swimming pool is chlorine. It’s hands down the most effective and widely used one. In fact, if you have a saltwater pool, then you have a chlorine pool because your saltwater generator turns salt into chlorine.

However, if you don’t have a saltwater pool, you can add chlorine using 3″ tablets in either your skimmer basket or a chlorinator. And we recommend that you use a chlorinator (here’s our favorite one).

Our Top Pick
3-Inch Stabilized Chlorine Tablets

Stock up and save money on chlorine tablets for the season by getting the standard 3-inch stabilized chlorine pucks.

If you want to reduce your chlorine usage by 50%, then we recommend using PoolRX. This device drops into your skimmer basket and adds minerals to your water. This allows you to keep your chlorine level between 0.5 and 1ppm instead of the normal 1 to 3ppm.

Our Top Pick
Pool RX: Reduce Chlorine Usage by 50%
$63.13

A simple device you add to your skimmer basket that supplies sanitizing minerals to your pool water so you can reduce your chlorine usage. Allowing you to only use 1ppm of chlorine.

If you have a smaller pool (under 10,000 gallons), then you can use granular chlorine for a hot tub.

Pool Shock

When your pool starts to smell like a hotel pool, it’s time to shock your water. Your pool actually shouldn’t smell like anything. This chemical smell means your sanitizer level is too low and is no longer doing its job.

Giving your pool a shock will bring sanitizer levels up where they need to be, kill bacteria, and ensure your water is clean. It can also help address mild cases of algae.

To accomplish all those things most effectively, choose a calcium hypochlorite or cal hypo shock. Prevent the dreaded hotel pool smell by shocking your water once a week, or at least once every other week. The more you use your pool, the more often you’ll need to shock it.

You’ll also want to shock your pool after major water level changes, pool accidents involving someone’s bowels, severe rainstorms, or when you need to kill pool invaders like algae. Here’s how to shock your swimming pool.

Our Top Pick
Calcium Hypochlorite Pool Shock (Cal-Hypo Shock)

This fast-acting, quick-dissolving swimming pool shock from DryTec kills bacteria, controls algae, and destroys organic contaminants in pools. It comes in easy-to-use 1-pound bags.


Use the entire contents of the bag when opened. If any granules settle to the bottom of the pool use brush to disperse them. Add the right dosage of this product during evening hours while the filter pump is running.

If you have a smaller Intex style pool or don’t have any current water issues, you can use non-chlorine shock which only takes 15 minutes to work. Here’s our favorite non-chlorine shock.

Our Top Pick
In The Swim Chlorine-Free Oxidizing Pool Shock 24 x 1 Pound Bags

Powerful oxidizing agent that eliminates combined non-sanitizing chlorine (chloramines) and provides higher free chlorine levels. Helps eliminate algae growth as well as harmful bacteria. Ideal for use with chlorine or bromine sanitized applications, weekly maintenance, and will not affect other chemical levels

Our Favorite Pool Cleaning Gear

This is our collection of the best pool cleaning gear that every homeowner must-have. We’ve researched and picked what we thought was the best quality gear on the market.

Telescopic Pole

Telescoping poles are versatile cleaning support tools, especially since most come with the option for interchangeable heads. This means you only need one pole to use a pool skimmer, manual vacuum, or pool brush.

Depending on the width of your pool, you won’t have to constantly walk around the deck to chase debris. You’ll also have the ability to shorten the pole for cleaning tasks that require a little less reach and more control, like vacuuming the pool steps.

Our Top Pick
Telescopic Swimming Pool Pole

Get those hard to reach places with your leaf net, vacuum, or brush. This professional-grade telescopic pole is what the pros use to clean pools thoroughly.

Pool Skimmer (Leaf Net) and Brushes

The most used tool in pool maintenance is the skimmer/leaf net. It attaches to a telescopic pole so you can collect debris off the surface of the pool. And there are two types:

  1. Leaf Net: Deep net to catch a lot of debris.
  2. Skimmer: Flat net just for a quick surface skimmer.

We like using leaf net skimmers so you don’t have to keep emptying the skimmer as you clean. You can use a leaf net in one consistent motion.

Our Top Pick
Heavy Duty Pool Leaf Net

It's a deep and durable leaf net pool skimmer that can collect a lot of debris all in one skimming. It also includes a lifetime guarantee. This is what the pros use!

Best Pool Skimming Technique

The other frequently used tool is a brush. And there are two types as well.

  1. An algae brush has stainless steel bristles that will easily break algae’s hold on walls, steps, and wherever else it may be hiding. Important: Stainless steel algae brushes are best for concrete or gunite pools.
  2. A regular nylon bristle pool brush if you have a vinyl liner to avoid damaging it.
Our Top Pick
Algae Brush with Stainless Steel Bristles

Perfect for getting rid of algae. For concrete pools only!

Our Top Pick
Heavy Duty Round Pool Brush

The wide pool brush has 360 degrees of strong bristles to clean hard-to-reach pool surfaces fast, including steps, ladders, slides, diving boards, and tough corners/crevices in every type of pool. This one-of-a-kind pool brush eliminates back and hip pains associated with one-sided brushes.

Manual Pool Vacuum Head and Hose

Most compact vacuum cleaner heads are compact, giving you more control when you’re cleaning your pool. Sure, an automatic cleaner can save your time a muscle strain, but it might miss hard-to-reach spaces. A manual option in your pool supplies can help you spot-clean minor problem areas before they become major problem areas.

Our Top Pick
Concrete Pool Flexible Vacuum Head

Designed to clean concrete and fiberglass pools. The vacuum head has a flexible design enabling it to fit the contour of your pool and will not scratch or damage.

Our Top Pick
Weighted Butterfly Pool Vacuum Head

The weighted triangle pool vacuum head is a great way to clean your pool. The weights on the bottom of the vacuum head help to keep it in place while vacuuming.

Buy Now On Amazon
If you click this link and make a purchase, we earn a commission at no additional cost to you.

Tip: To use a manual vacuum, you’ll also need a telescoping pole and a vacuum hose.

Our Top Pick
Heavy Duty Pool Vacuum Hose

Made to last and designed to work with standard swimming pool vacuum head and telescopic pole for manual vacuuming. The swivel cuff end connects directly onto the vacuum head, whereas the non-swivel end connects to the skimmer.

Automatic Pool Cleaner

OK, so you don’t absolutely need this one as long as you have a manual vacuum. But an automatic pool cleaner can save you a lot of time and effort by helping to keep your pool clean, even when you’re not around.

Think about it. You have a rough day at work, traffic on the way home is terrible, and all you want to do when you finally get home is take a refreshing dip in your clear, clean pool. Except, while you were at work, a bunch of leaves and other stuff blew into the water, so before you can relax and enjoy your pool, you have to vacuum it. Ugh. You may as well stay inside.

But if you had an automatic cleaner zipping around the pool all day, you’d come home to clear water ready for you to dive in with no hassle at all. We think this makes it one of the most helpful pool supplies you can have in your pool care arsenal.

Our Top Pick
Dolphin E10 Automatic Robotic Pool Cleaner for Above Grounds
$599.00

Designed for above ground swimming pools up to 30 feet. It takes less than 2 hours to clean your pool with built-in water filtering and scrubbing.

A lot of pool stores will have a ton of supplies they say you absolutely need to get the job done. And you may find other pool supplies later on that you can’t live without. We all have our own ways of handling pool maintenance with little tweaks here and there to reach the same end goal: a clean, healthy pool.

You’ll certainly add to your stock of pool supplies as you become a more seasoned pool owner. Just make sure you have the essentials to keep your pool clean, and you’ll get a lot more enjoyment out of your investment. And isn’t that the way it should be?
