description Instructions
- Drop your CYA Remover Pouch in the skimmer basket.
- Adjust your pH, if necessary, so that it falls in the 7.2 - 7.6 range.
- Stop using any chlorine with stabilizer. Switch to bleach or shock while using the CYA Remover filter.
- Run your pump 24 hours/day, or as much as possible (It's all about contact time with this filter!) with a flow of at least 4-6 gpm (average flow rate of a garden hose, for comparison)
- Use CYA test strips that test as high as 250 - 300 ppm, such as LaMotte, Aqua-Check, or Taylor. Check your CYA levels once a week. Your CYA levels should come down at the rate of 10-20 ppm/week on average, depending on pool conditions.
- When the pool reaches your desired CYA level, simply toss the bag in the garbage.

GreenStory Global's CYA remover is the easiest way to end chlorine lock without needing to drain your pool. Simply drop the pouch into your pool skimmer and let it do all the work. The CYA remover pouch works by adsorbing the CYA out of the water as it filters through the pouch. It works at any temperature and will reduce the CYA by around 10ppm per week without any other impact on pool chemistry. GreenStory Global CYA remover is made in the USA. Use 1 lb. bags for general maintenance and small pools, and 1.5 lb. bags for very high levels of CYA or larger pools.
Why is too much CYA a Problem?
CYA (Cyanuric acid) is a chlorine stabilizer and buffer commonly used to maintain chlorine levels in swimming pools, and some stabilized chlorine tablets like Trichlor and Dichlor tablets have CYA mixed directly in with the chlorine. This can become a problem if the CYA level rises above the 30-50 ppm as too much CYA will prevent chlorine from effectively sanitizing the water leading to an increase in bacteria, algae, and cloudiness of the water.
Historically the most effective way to reduce the level of CYA in your pool was simply to drain the pool halfway or more and fill it back up to dilute the concentration of CYA remaining. This could be a costly and time consuming process
