How much chlorine do I put in a 1000 gallon pool?

If the water is clean and clear, then add about 3 oz of liquid chlorine per 1000 gallons of water – while the pool filter is running. This should give you a chlorine level of about 3 ppm.

How many gallons does a 1 chlorine tablet treat?

5,000 gallons

In most cases, you’re best off with 3-inch chlorine tablets, as one single tablet can treat up to 5,000 gallons of water. On the other hand, 1-inch tablets contain far less chlorine (about half as much as 3-inch tablets), so they’re better suited for smaller indoor pools and spas.

How many gallons does a 3-inch chlorine tablet treat?

5,000 gallons

3-inch chlorine tablets are ideal for large pools because one tablet can treat about 5,000 gallons of water on average. Pools with more than 5,000 gallons of water can use more than one chlorine tablet, though the dissolving time is much slower for 3-inch tablets.

How much shock do I need for a 1000 gallon pool?

A 1000 gallon pool may just need 0.13 ounces or a little higher. Instead of using Clorox, I recommend regular liquid chlorine bleach or Sodium Hypochlorite for daily shocking, Clorox has lots of Calcium Hypochlorite and is good only for killing algae.

How much baking soda do I put in a 1000 gallon pool?

As a reminder, you want your pH to be between 7.2 and 7.8ppm and your free available chlorine to be 1-4ppm for safe swimming.

How soon after filling a pool Can you swim?

Chlorine/non-chlorine chemicals – When adding chlorine or non-chlorine chemicals to “shock” your pool after a fill-up, wait about 24 hours or until levels are approximately 5 ppm.

Test the Chlorine Level



Chlorine is essential for pool water because it kills harmful algae, bacteria and microorganisms. Unfortunately, chlorine breaks down when exposed to the sun and chemicals from sunscreen, sweat and more. A pool should have a chlorine level between two and four parts per million (ppm).

Can you put too much chlorine in a pool?

Having too much chlorine in your pool water can be dangerous. Exposure to high levels of chlorine can cause lung irritation, skin and eye damage, and provoke asthma. Not only is it bad for your health, but it can be bad for your pool due to the increase in chlorine.

Can I swim in my pool if the chlorine is low?

As mentioned above, you could probably swim in a pool without chlorine without any major health issues. However, long-term use of a pool lacking chlorinated H2O could make you sick or, at the very least, contribute to rashes and other types of skin irritation.

How often should I add chlorine to my pool?
