Generic

$49.99

$54.99
(9% Off)

More Details
Main highlights
- WILL NOT work with salt water pools
- Skimmer Basket: Keep skimmer basket clean, make sure no debris has built up on the surface of the CYA pouch, if you notice build up on the outside of the pouch you may take it out wash it off or flip the CYA reducer pouch for best flow.
- READ EACH BULLET POINT CAREFULLY OR PRODUCT WILL NOT WORK
- Pump/Motor: Run the pump 24/7 on slow speed if possible you want to reduce RPM as much as you can, remember run pump 24 hours a day, it takes alot of time for the whole pool to circulate through the pouch.
- Chlorine: if required only use liquid chlorine and add it at the opposite end of where the skimmer basket is, remove chlorine pucks from skimmer basket, do not use products with stabilizer (CYA) , high amounts of chlorine can stop the product from working correctly.
- Be Patient: Check levels after 1-2 weeks, if you do not see a reduction ensure you have a high end test strip that can get a full reading and then contact us for any troubleshooting.
- Adjust ph: ph value must be between 7.2-8.0 BEFORE adding the CYA pouch and the levels must remain in this value to stay affective
