## Overview

GreenStory's Cyanuric Acid Reducer is a unique filter pouch filled with carbon and proprietary resin that absorbs excess CYA from pool water, reducing levels by approximately 15 ppm per week. It requires strict adherence to pH control (7.2-8.0), continuous slow-speed pump operation, and use of liquid chlorine only. Designed to fit in the skimmer basket, it offers a chemical-free alternative to draining your pool, but results depend heavily on following detailed usage instructions.

## Description

Unlike the competition's chemical CYA reducer, GreenStory Global's Cyanuric Acid Remover is a filter that sits in the skimmer basket. The filter pouch is filled with carbon and a proprietary resin that absorb CYA from the water. The filter will reduce the total CYA in the pool by about 15 ppm per week. Once the pool reaches the appropriate level, simply throw the filter away. This product does work, but you must follow the directions carefully for it to be effective. Also remember it takes time to work 1-2 weeks to see a significant drop in CYA and you must use a high end PPM test strip to check levels if your CYA levels are above 300ppm they will not even register. If you follow the steps provided in the bullet points and instructions the product will work or we will give you a full refund.

Review: Using CYA filtering powder to get rid of CYA without Draining the pool. - This stuff works. Period. Run pump slowly, run around the clock, make sure no CYA is in the chlorine feeder, add a little liquid chlorine at far end from the skimmer, just enough to show some green with your test kit. One important thing. Liquid chlorine has a pH of about 18 so it will run the pH up if you don't pay attention. At least once a day check your pH and your alkalinity. Get alkalinity up to about 100 by adding sodium bicarbonate as needed. Toss the powder into the shallow end of pool where the CYA is located. If pH is getting close to 8.0 add about a cup and a half of muriatic acid at deep end but no sooner than 4 hours after the liquid chlorine was added. After a few hours check both. Check CYA once a week at store. Mine dropped from 143 down to 46 where it is now. Expect 10 to 15 ppm drop each week. Once you return to CYA tablets you shouldn't need any more liquid chlorine. But on long, hot days the feeder may not be adequate to break the 1 ppt chlorine level so a little back up chlorine may be needed. The pH of trichlor is about 3 which should balance the impact of chlorine and alkalinity. Make whatever adjustments you need to keep the pH in the 7.2 to 7.8 range. Never add CYA to your pool. 30 is plenty adequate but 50 is okay
Review: Did Not Work At All - This did not work at all. I have a 28,000 gallon pool with two skimmers, a variable speed pump, and an auto cover. I used one filter pouch in each skimmer for 5 weeks but it did not lower my CYA at all. The instructions are ridiculous. It says you need to keep your chlorine at 0-1ppm, and run your pump at 1500 RPM, which is about 30% slower than I would normally run. The problem with that is that if you already have high CYA and you try to maintain 0-1ppm of free chlorine and your only running your pump at 1500 RPM you will end up with cloudy water and/or an algae bloom, which is exactly what happened to me after following their instructions for only two days. I then had to shock my pool and wait a few days for the water to clear up. After that I turned my pump back up to 2100 RPM (45gpm) and maintained free chlorine at 2-5ppm. I was only using liquid chlorine, no pucks so I was not adding anymore CYA to my pool. Every time I added more chlorine I would removed the filter pouches and continued running my pump for 12-24 hours before putting the pouches back in. Other than that the pouches were in my skimmers and I was running my pump 24 hours per day. When I started using the filter pouches my CYA was around 110. After 5 weeks my CYA was measuring 100. I'm quite certain the only reason it dropped 10 points was due to the fact that I was also diluting my pool with rain water every time it rained by directing the hose of my cover pump back into the pool. I would not waste your time or money on this product, especially after reading all of the other reviews on desertcart and other sites. Reviews are very mixed with most stating this did not work. I will just resort to partial drain a refill to bring my CYA levels down.

## Features

- READ EACH BULLET POINT CAREFULLY OR PRODUCT WILL NOT WORK
- 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
- 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.
- 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.
- 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.
- 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.
- WILL NOT work with salt water pools

### ⭐⭐⭐⭐⭐ It actually works. Follow the directions. Have patience.
*by C***N on March 22, 2025*

I started out with 170ppm cya. This happens every year. After 3 days it dropped to 90ppm. 7 days we are at 50ppm. Follow the directions. First thing I did was back flush the pool filter. I dropped poolrx algicide in for a few days. Dropped in this beauty and ran the pump at 1500rpm 24 hours a day. Zero chlorine. It does take time. But it does work. I did let the leaves in the skimmer fill the sides of the basket so most of the water goes through the device. Ran a electric pool vacuum robot as well to stir the water up. I am extremely impressed with this product. It has saved me over 600$ and proved the pool store wrong.
