If I have a 10,000 gallon pool and my chlorine test kit indicates i have 4ppm - can you tell me how many gallons of chlorine I have in the pool.

thanks dbl

Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

So we know that:

120,000 gallons of water = 1,000,000 pounds

1 ppm = 1 pound per 120,000 gallons of water

you need 4ppm for 10,000 gallons so:

10,000gallons/120,000=.08 pounds of water

.08 pounds of water x 4 (you need 4ppm) = so you have .33 gallons of chlorine in the pool.

I could be wrong but that is how I see the formula working out.

120,000 gallons of water = 1,000,000 pounds

1 ppm = 1 pound per 120,000 gallons of water

you need 4ppm for 10,000 gallons so:

10,000gallons/120,000=.08 pounds of water

.08 pounds of water x 4 (you need 4ppm) = so you have .33 gallons of chlorine in the pool.

It's a lot simpler than that.

You have 4 parts per million. That means that if your pool held 1,000,000 gallons, it would contain 4 gallons of chlorine at 4ppm.

If it held one-tenth as much - 100,000 gallons - it would contain 0.4 gallons of chlorine.

If it held just one-tenth of that - 10,000 gallons, which is what you have - it would contain 0.04 gallons of chlorine.
