Putting lots of chlorine in your pool? You need to consider following factors that eat up chlorine fast:
- Heavy Usage.
- Due to low pH level, chlorine becomes unstable.
- If Cyanotic Acid level is less than 25 ppm, it will lose 2-4 ppm of chlorine every day.
- Warmer water in pool due to sun, will cause bacteria to grow quicker.
Proper filtration and backwashing is must to determine the total chlorine.
Dead algae if in water, is oxidized by chlorine. Organic debris is also one of the reasons so vacuuming and filter backwashing is necessary.
To overcome the chlorine demand issue you need to add stabilizer, clean the skimmer basket and filter, add a phosphate remover and test & balance pH and alkalinity levels.
