How to Fix a Green Pool

Written by System X Designs. Posted in Blog

If the pool is free of algae, the green tint indicates that something is slightly out of balance or there is a presence of a high level of phosphates that can also lead to redundant algae problems. Typically the bleaching effect of chlorine compensates for an out of balance condition, keeping water blue in spite of possible problems. Since one of the benefits of E-Z POOL® is that it does not contain bleach, the following is a list of things to check when troubleshooting a pool with green tint:

1. Check the filter. A clean filter is always the first step in correcting a problem with E-Z POOL®.

2. Test sanitizer level. If the pool is lacking sanitizer, there may be a tendency for the water to get a green hue. If the sanitizer is too low, the pool may take on a flat look and then turn a light green tint. When experiencing a green tint from low sanitizer level, try increasing the sanitizer level to at least 3.0 ppm with the addition of a dichlor shock.

3. Test for phosphates. A high phosphate level is often the cause of stubborn green tint in E-Z POOL® water. Use Revive!® to resolve this problem quickly and effectively.

4. The level of calcium contributes to the “body” of the water. If the pool water lacks body, it may not effectively reflect the UV rays of sunlight to produce the blue tint most commonly associated with swimming pools. Here again, if the green tint is due to chemical imbalance and sufficient oxidizer is present, the calcium level may be too low.

Calcium level should be adjusted to 350 ppm. Always adjust balance before dosing with E-Z POOL® and allow water to reach new calcium balance prior to E-Z POOL® application.

5. Test copper level. Excessive copper levels may contribute to a green hue or tint. Check the copper level and if it exceeds 0.8 ppm, treat with Revive!® to reduce.

6. Test pH and total alkalinity. If pH is high or low relative to calcium, and total alkalinity is too low relative to pH and calcium, this could result in a green tint. Adjust to recommended levels.

  • "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!”
