Review: Simply no effect at all although my pool was absolutely perfect in terms of temperature, ph, chlorine etc. There really is no substitute for drain and refill. Review: I used this to reduce the level of the UV protection in the pool. It had gotten so high the chlorine wasn't doing its job even when the residual level was high. The other option I knew of was to partially drain the pool and replace the water which is more expensive and a waste of water. I have what I consider a normal sized pool and it only took half a bag. After you add it wait a week or so to test. It is not an instant thing. ## Features - Natural cyanuric acid reducer powder reduces acid levels by up to 50 percent - Helps eliminate chlorine lock due to high cyanuric acid levels and allows sanitizers to be more effective - Non-polluting, and leaves no residue with a mildly sweet and earthy odor feature - Reduces acid levels by disintegrating it at a molecular level and causes no adverse effects on pool - Suitable for outdoor commercial and residential swimming pools with a 50,000-gallon water capacity ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00YJP92NI | | Brand Name | Bio-Active Products, Inc. | | Customer Reviews | 3.4 3.4 out of 5 stars (1,773) | | Item Form | Powder | | Item Type Name | Cyanuric Acid Reducer | | Item Weight | 16 Ounces | | Manufacturer | BIO ACTIVE PRODUCTS INC | | Product Benefits | Reduces acid levels, eliminates chlorine-lock, allows sanitizers to be more effective, and is non-polluting, non-allergenic, and odorless, while reducing acid at a molecular level. | | Unit Count | 16 Grams | ## Product Details - **Brand:** Bio-Active Products, Inc. - **Item form:** Powder - **Item weight:** 16 Ounces - **Number of Items:** 1 ## Images ![BIO ACTIVE PRODUCTS INC Bio-Active BA-CAR-16 Non Polluting 100-Percent Cyanuric Acid Reducer Powder for Commercial and Residential Swimming Pools, 16 Ounces - Image 1](https://m.media-amazon.com/images/I/61aby5Z6soL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Can you swim after using the product?** A: We had folks swimming after it was put in. However, I never got the product to work. Found it to be a failed and expensive mistake. Ended up dropping the water in the pool and refilling it to get the Cyanuric acid down. **Q: Does this work with a uv sanitizer ?** A: This product doesn't work at all. This product is a waste of money. Leslie's Pool Supplies used to carry this product in their brick & mortar stores but ceased carrying it due to all the complaints they about this not working. The only way to reduce the cyanuric acid level in your pool is to change at least 25% up to 100% of the water in the pool. **Q: Can this be used in a covered pool?** A: Yes, you can use it in a covered pool. **Q: Does the water gets cloudy after application of the product?** A: Not in my experience. It also didn't lower my cyanuric acid levels sufficiently. I ended up pumping out some water and refilling. ## Customer Reviews ### ⭐ Review *by M***Y on 15 October 2025* Simply no effect at all although my pool was absolutely perfect in terms of temperature, ph, chlorine etc. There really is no substitute for drain and refill. ### ⭐⭐⭐⭐⭐ Review *by L***N on 12 January 2023* I used this to reduce the level of the UV protection in the pool. It had gotten so high the chlorine wasn't doing its job even when the residual level was high. The other option I knew of was to partially drain the pool and replace the water which is more expensive and a waste of water. I have what I consider a normal sized pool and it only took half a bag. After you add it wait a week or so to test. It is not an instant thing. ### ⭐⭐⭐⭐⭐ Review *by R***M on 19 May 2017* Worked as expected - will need another bag though, have just a bit more to go before I reach the right number. When I purchased, my CYA was around 300 or more (lets put it this way, I was way passed the 100 mark on the tube) - I have a 10k and the bag says it will treat up to 25k ... well, I am now at 100. So, it works, but you may need more than one bag depending on size of pool and amount of CYA in pool. Also you should note that it can take up to 10 days to lower your levels - so I will have to wait another 6 days before adding a second bag to be sure. Leslie's charges $49.95, so this is a good price. Now, this wasn't the only thing wrong with my levels, so how it worked for me, may not be what you need (and I suppose I won't really know if it works until I add the second bag and see if it drops to where it needs to be) How I did it : I took out my chlorine duck and let the pool do it's thing (running 8 hours a day) for about 10 days with no chems. Then I washed my filters thoroughly and added the Phos Killer (from walmart $9 - kills 1000 ppm) and ran the pool for 48 hours non stop Then I turned the system off for 24 hours and let the pool sit After 24 hours I washed my filters again and then added my duck back into the pool and let the pool run a normal cycle for another day before FINALLY adding the whole bag of CYA into the skimmer and let the pool run normal cycles for 72 hours before adding the Alkaline Up - then ran it for 12 hours and when I took my water to be tested everything was back to normal except I'm now at a 100 on my CYA rather than 300, so if after 6 more days the levels aren't where they need to be, I think one more bag should do it This is the information I was given about using the Bio-Active product::: Bio-Active uses natural cultures to reduce your CYA, be sure your pool will be habitable for the the organisms to do their job. You should also not that your chlorine will attack these organisms, so it's best to be in normal or low ranges. In addition to providing livable ranges for the active ingredient to thrive in, make sure you take note of the information below to get the most out of each dosage: » Do not add shock or algaecides 7 days prior to application. » Works best in an outdoor pool, uncovered for at least 7 days. » Bio-Active does not work in mineral system pools. » Make sure your pool is free of algae or other contaminants. » Be sure to shut off UV, ozone, and chlorine feeders 15 minutes prior to, and 3 hours after, applying Bio-Active Safely lowers CYA levels within 10 days without needing to drain the pool. Eliminates chlorine lock due to high CYA. Use 1 bag for up to 25,000 gallons. Works best with water over 65 degrees Fahrenheit. I hope this helps anyone having troubles - I know it's a bear of a situation and VERY time consuming .... Don't you remember going to the lake and swimming or fishing, never once thinking of what microscopic things lay in wait? Having never once thought of PH levels or the like? We lived, didn't get sick and kept going back (this is in no way meant to diminish anyone's adverse reactions to such events - merely a personal reflection). Do you think lake or ocean water is cleaner than your pool? Yet here we all are, busting our hump, spending hours and hundreds of dollars even when our pools are sparkling clean and we can't see anything wrong (as is my case - before all this process I mentioned, my water was clear, had no odor and looked great ... but it had been a while since I'd had it professionally tested and wasn't sure if MY test stuff was still optimal, so I took it in and BAM! There was evil lurking in that falsely serene setting of a sparkling pool ready for swimming. Sounds fishy to me, but - here I am, tired, annoyed, poorer and ready to just fill it in and plant grass! ## Frequently Bought Together - Bio-Active BA-CAR-16 Non Polluting 100-Percent Cyanuric Acid Reducer Powder for Commercial and Residential Swimming Pools, 16 Ounces - Cyanuric Acid (CYA) Reducer for Pool and Spa, Removes CYA Through Filtration 1IB - EASYTEST 7-Way Pool Test Strips, 150 Strips Water Chemical Testing for Hot tub and Spa, Accurate Test Bromine, Total Alkalinity, pH, Free Chlorine, Total Hardness, Cyanuric Acid, and Total Chlorine --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/440139695-bio-active-products-inc-bio-active-ba-car-16-non](https://www.desertcart.pl/products/440139695-bio-active-products-inc-bio-active-ba-car-16-non) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-11*
