BROMINE: BUYER’S GUIDE & FAQ

Switching from chlorine to bromine is easy. You just need to stop using chlorine and start using bromine tablets. If you have a chlorinator or tablet feeder, you should replace that so the two chemicals don’t come into contact. [Shop All Bromine]

You want to keep your bromine level between 2 and 4 ppm. For spas, it should be slightly less at 1 to 3 ppm. [Shop All Bromine]

You can test your pool's bromine the same way you test the rest of your pool’s chemistry. You may need to purchase additional bromine testing strips if you’re current kit or strips don’t include a bromine test. [Shop All Testing Kits]

For proper maintenance, you should add bromine to your pool every 5 to 7 days. For spas, you should add brome every 2 to 3 days. Testing should be done at least as frequently as you add bromine. Testing will allow you to gauge if your bromine levels have dipped and if you need to add more. [Shop All Bromine]

This is determined by the size of your pool and the level of bromine. The rule of thumb is you should add 17 tablets, 1” in diameter, for every 10,000 gallons of water. For spas, we recommend adding 3 tablets for every 300 gallons.

As you add bromine to your water, you’ll want to make sure you’re checking the level of bromine already in your water to adjust accordingly. [Shop All Bromine]

You’ll need to find the volume of your pool. Here’s a quick formula you can use:

Length x Width x Average Depth x Multiplier = Volume in Gallons

• Multiplier for rectangular and square pools is 7.5
• Multiplier for oval pools is 6.7
• Multiplier for round pools is 5.9

Note: All measurements should be in feet, including the depth. For above ground pools, assume that the water depth is 6” less than the wall height, so if your pool is 48”, assume the depth is 3.5’, and for a 52” pool, use 4’.

If math isn’t for you, take a look of the chart below featuring common pool sizes and how many gallons of water each size holds.

You can! You can shock a bromine pool with chlorine or chlorine-free shock to break down contaminants or kill bacteria. This is done just like in a chlorine pool — but without worrying about the breakpoint chlorine level. Chlorine shock can also be used as an algaecide since bromine lacks those properties.
