Buying Guide
If you’re considering buying liquid chlorine for your pool there are a few things you should take into consideration first. Before you make your purchase, you’ll need to make sure you have the right amount for your pool’s size. The next thing you’ll want to take note of is the pH level of your pool water. You can test the pH level yourself with a simple test kit, or you can ask a pool professional to do it for you. Another important thing to consider is how much sunlight your pool gets. Sunlight can actually break down chlorine, which is why it's important to use more in pools that are in direct sunlight all day long. Most liquid chlorine is available in 4 and 8-gallon packs that will both last you longer and save you money. You’ll also want to consider the features of the liquid chlorine you’re thinking about purchasing. Some liquid chlorine brands require you to mix them before use. Other brands are ready to use with no mixing required. If you want to go the less complicated route of chlorinating your pool, a ready-to-use liquid chlorine will probably be the better option for you. Other liquid chlorine features include a cloud-free formula and commercial-grade strength. It is up to you to decide which features matter most. Lastly, you’ll want to consider the reviews from other customers of the liquid chlorine you’re selecting. Reviews will let you know how well the product has worked for others and what purchasers have to say about it.
