The brown staining in your pool is caused by oxidized iron, which is probably getting in your pool from the well. The oxidizer in E- Z POOL shocks out more contaminants than regular chlorine shock. Sometimes, especially pools filled with well water, this can cause an issue that was previously unknown while on chlorine because it is not as versatile as the E-Z POOL®. In most cases, the problem can be fixed rather easily.

When you used ascorbic acid before, it was the right thing to do, unfortunately you weren’t told that the job was only half done. Ascorbic acid removes the stain rather easily BUT once the stain is removed, the molecules that formed the stain are still in the pool water. They have just been dissolved. Unfortunately sand filters only filter out particles that are 20-25 microns and larger, oxidized iron is in the 2-4 micron range. So, your filtration system needs help removing the particles that caused the stain out of the pool water. The fastest and easiest way to do this would be to:

1. Treat your pool with ascorbic acid, you shouldn’t need more than a pound. It should work within an hour or two. Once it has been circulated throughout the system.

2. Once the brown stain has been lifted, turn off the pool pump.

3. Spray a 16oz bottle of Revive (removes the iron particles by dropping them out of solution and in to a sediment on the bottom of the pool so you can vacuum it to waste, removing it for good) over the top of the pool.

4. Leave the pool off for at least 24 hours.

5. Vacuum the debris out of the bottom of the pool while your sand filter valve is on waste.

6. Follow the weekly directions for the E-Z POOL®  that your local store has given you.

You should also have a bottle of REVIVE! at the house for whenever you fill up your pool due to evaporation or splash out. Simply attach the Revive to the end of your fill hose and spray the product over the top of your pool water, covering the pool twice, REVIVE! will capture the particles from your well water that shouldn’t be in your pool water and send them to your filter for you so that you do not have to go through this huge procedure over and over.

  • “Just wanted to thank you for a great product. After four weeks of trying several different products and also adding way to much chlorine, we can finally see the bottom of our pool. Added REVIVE! at 6PM last night, by the time we went to bed, we could notice a difference and when I got up this morning everything had settled to the bottom. Used the vacuum for about an hour this morning and were swimming this afternoon. Will probably have to vacuum once more, but so glad this product was recommended to us.”

  • “Easy, simple, worry free…these all describe how my pool maintenance has been since I started using EZ POOL! I have a big pool and it is not a big job with E-Z POOL, just once a week. Once the pool is open and clear in the spring, I just have Caryl’s experts test my pool sample once a week to make sure the balancing chemicals and pH are good. Algaecides are not needed. Brush, brush, brush, as Caryl recommends and my pool is beautiful all summer! Also, it is gentle to the skin and does not effect your hair color. I highly recommend E-Z POOL!”

  • “I have used the EZ Spa now for four years. It is the best spa treatment I have ever used. It makes the water feel really soft and refreshing. I use it once a week and forget it. My spa stays crystal clear. I love this stuff. Not to mention when you use EZ Spa you don’t have to buy so many other chemicals. I also noticed that EZ Spa is extremely gentle on the skin. I can’t say enough about how good this stuff is. Try it, you’ll love it!”
