1. Why is it important I test my water often?

Frequent testing = less problems.
Improper water chemistry can create several problems. Most common are the clarity of the water and the life span of the equipment. High pH can cause scale build up on the surface of the pool and any accessories. (light rings, ladders, etc...) Low pH can eat away at the equipment internally as well as the pool surface and accessories.
Low chlorine can cause cloudy water and eventually permit the growth of algae and bacteria in the pool.
Why does my pool have slow circulation?
Usually when the circulation slows in the pool it's due to a dirty filter.
Different types of filters need to be cleaned according to the manufacturer's instruction. Sand filters can be backwashed, D.E. filters can be backwashed and recharged (add new D.E.) and cartridge filters require the removal and cleaning of the cartridges.  Chronic pool problem can be due to improper installation or under sizing the equipment per the pool size.

2. Why is the chlorine I've added gone the next day?

The sun and excessive bacteria can cause the chlorine dissipate quickly. Adding the recommended amount of stabilizer/conditioner   to the water will reduce the loss of chlorine.

3. Why is my pool water cloudy?

When a pool starts to cloud it's usually because the chlorine is going from .5 to 0. Other factors can attribute to it such as improper filtration. The Ph being too high can cause the chlorine to be ineffective. Not running the equipment long enough. Your pool should run at least 12 hours a day during the peak summer months. Once you've established the problem run your system constantly until the pool clears.
We recommend running the pump 24 hrs continuous. Turn over rate (Turning over all the water through the system) may not be achieved with 12 hr per day operation causing lack of filtration and chronically returning problems. Swimming pool pumps are designed to run 24 hrs a day and will not reduce their life span by doing so.

4. Why is my pool green?

When a pool is green it has an over abundance of algae. Super shocking the pool with a larger dose than the normal shock should kill any algae or bacteria. See manufacturer's recommended dosage for super chlorination. Salt systems are designed for normal maintenance. Follow the same procedure as a chlorine pool for super chlorination.
Shocking the pool in the evening when the sun is off of the water is the most effective. Follow the shock treatment the next morning with an algaecide containing at least 30% concentration. This will help inhibit future outbreaks.
