Top 5 List of Strange Things that Affect Your Pool Water

If you’re having water trouble and can’t figure it out, here are a few extraordinary things you might check:

  1. Don’t assume tap water is good water for a pool. The typical hardness in Phoenix tap water is as high as 1000ppm — 700ppm above the high end of the maximum concentration.
  2. The circulation time required to keep a pool clean and clear is normally 10 hours a day. This varies due to bather load, water temperature, wind, rain, sunlight and pool chemistry itself.
  3. Some pool chemicals actually contain minerals that can add to a calcium problem.
  4. There’s been plenty of talk and about removing phosphates from pool water. In truth, phosphates do not consume chlorine and do not combine with chlorine. Rather, Phosphates promote the growth of algae (the green, slippery stuff in a pool) which then consumes all the chlorine as the chlorine tries to destroy the algae. The net result is that you can be left with less than the desirable amount of chlorine in your pool.
  5. In a salt chlorinated pool, UV light will speed up the conversion of chlorine back to salt. A chlorine stabilizer (sort of like sun block) will dramatically slow down this conversion keeping more chlorine available for a longer time. Without this proper protection, the life span of the chlorine is greatly reduced.

Remember: Clear water doesn’t mean good water, but good water will be clear.

Algae Problems in your Pool?

By Costa Rica Pools and Construction

Algae are single-celled plants that live in water. Following are conditions that may contribute to algae growth: High pH (over 7.6), low or no Free Chlorine residual, poor water circulation or short filter.

PROBLEM: Green algae is the most common type of algae. Usually floats freely in water but can grow on the surface as well.  It causes “pea soup” green water.

SOLUTION:  Adjust the pH of the water to 7.2 to 7.6 and be sure the Free Chlorine residual is 1-3 ppm.  Algae treatments will be much less effective if the pool cannot maintain a chlorine residual. Each algaecide has specific application information on the label. Read and follow label directions.

Use the following algaecides:

  • Tri- Coppercide from Costa Rica Pools

Success will be improved with proper brushing of the pool. Run the filter for 24-48 hours following treatment or until the water clears. Repeat treatment as necessary. Add Sparkling Blue water clarifier to help clear the water of dead algae and debris. Thereafter, make sure that the pH is 7.2 — 7.6 and that the Free Chlorine residual between 1-3 ppm is maintained.

Four Important Steps to a Clear & Inviting Pool

By Costa Rica Pools and Construction

The four points below are the basics of excellent pool maintenance.  Pay attention to these areas to help your pool look its best.


Pool water must be circulated for your pool care products to work their best.  The more your water in motion, the harder it is for bacteria and algae to grow.  And the more water that passes through the filter, the more debris is captured.  The best time to circulate water is during the day, for 10 hours or more.
