Review: Great quality DI Resin and at the time of this review fast shipping! - I've been keeping reef tanks for over a decade and in that time have learned a lot about water quality. Where I live we have hard water and the quality is rather bad. I also have a whole house water softener and while even being on city water without a softener everything in my home will run red from iron. I know rather sad... you can't expect better quality water from our cities anymore. I realized regular 4.5 pound refill bag was empty a little to late to wait on ordering one as the shipping is rather slow. At that time my TDS meter TDS = Total Dissolved Solids was already showing around 10 and this was the best option I could find on desertcart with quick shipping and price but more expensive than only buying the resign separate from the containers and refilling yourself. This DI-Resin brought my TDS right back to 0 and I've experienced no issues after using it for several months and I'm still using my first replacement filter. The life the product seems to be in along the same lines as the other brand I usually use. Thumbs Up - Great Product Review: Excellent Filters - I purchased these RODI filters to put in Frigidaire canisters to use for washing my vehicles. What a difference they made for removing the water spots on my car, our water has Lots of calcium and mineral deposits in it which left an insane amount of water spots on my vehicles after washing ( I couldn't dry it fast enough) I'm using a 5 micron carbon pre-filter and then 1 RODI filter and what a difference it's made! I can literally let my car air dry with No water spots! I've used 1 filter so far and after 10+ uses it's still performing great. I plan on adding a 1 micron pre-filter to extend the life of the RODI filter. All in all I've made a car wash water filtration system for under $100.00 that works perfect with no reduction in water volume or pressure. I would recommend this product! ## Features - COLOR-CHANGING DEIONIZATION RESIN – AquaticLife Mixed-Bed Deionization Filter Cartridge contains positive Cations and negative Anions, each in a different color. DI Resin physically changes colors from Blue to Tan when the media is exhausted. - REDUCES TOTAL DISSOLVED SOLIDS TO ZERO – The deionization resin is necessary to reduce Total Dissolved Solids (TDS) to zero in the final stage of an RO/DI system. It uses ion exchange to remove TDS from water. - 10-INCH STANDARD SIZE FILTER – 10-inch mixed-bed DI filter cartridges fit popular RO/DI systems and the Aquatic Life Spot Free Car Rinse. The opaque housing allows for easy detection to know when it’s time to replace the resin. - THREE REFILLABLE CARTRIDGES – Cartridge caps unscrew to allow for refilling with AquaticLife bulk resin. Compatible with Captive Purity, Kent Marine, Seachem, Coralife, BRS, and most other residential or aquarium/hydro DI and RODI systems. - UNSURPASSED QUALITY AND SATISFACTION – AquaticLife manufactures an assortment of water filtration equipment. Every product that goes out the door meets our highest standards and quality. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B018F4R460 | | Best Sellers Rank | #38,060 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #246 in Replacement Under-Sink Water Filters | | Brand | Aquatic Life | | Brand Name | Aquatic Life | | Customer Reviews | 4.6 out of 5 stars 545 Reviews | | External Testing Certification | NSF | | Item Dimensions D x W x H | 2.75"D x 2.75"W x 9.75"H | | Manufacturer Part Number | 330237 | | Material | Resin | | Material Type | Resin | | Model Number | 330237 | | Number of Items | 3 | | Product Benefits | REDUCES TOTAL DISSOLVED SOLIDS TO ZERO | | Product Dimensions | 2.75"D x 2.75"W x 9.75"H | | Set Name | 3-Pack | | UPC | 810957012373 | | Unit Count | 3 count | ## Product Details - **Brand:** Aquatic Life - **External Testing Certification:** NSF - **Material:** Resin - **Product Benefits:** REDUCES TOTAL DISSOLVED SOLIDS TO ZERO - **Product Dimensions:** 2.75"D x 2.75"W x 9.75"H ## Images ![AquaticLife Color-Changing DI Resin Cartridges, 10 in, 3-Pack - Image 1](https://m.media-amazon.com/images/I/81U8S+dgWhL.jpg) ![AquaticLife Color-Changing DI Resin Cartridges, 10 in, 3-Pack - Image 2](https://m.media-amazon.com/images/I/8171J9gWV4L.jpg) ![AquaticLife Color-Changing DI Resin Cartridges, 10 in, 3-Pack - Image 3](https://m.media-amazon.com/images/I/71mG0rixD8L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great quality DI Resin and at the time of this review fast shipping! *by M***N on July 25, 2020* I've been keeping reef tanks for over a decade and in that time have learned a lot about water quality.

Resin does not work that way. These are NOT water filters in the classic sense. These REFILLABLE filters are to be used as the LAST filter RO water passes through to get 0/ZERO TDS DI or spot free rinse water. To be economical buy bulk resin and REFILL them when they are spent, as they are meant to be. It is much cheaper to use a car wash than to buy new the filters when they are used up. ## Frequently Bought Together - AQUATICLIFE Reverse Osmosis 10-Inch Mixed-Bed Color Changing Deionization Resin Filter Cartridge for RO/DI System Units, 3-Pack - AQUATICLIFE Aquatic Life Deionized Spot-Free Car Rinse Unit - Premium Water Deionizer for Car Washing - Spotless Car, RV, and Motorcycle Wash System - Flexzilla Garden Lead-In Hose 5/8 in. x 3 ft., Heavy Duty, Lightweight, Durable, ZillaGreen - HFZG503YW-E --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co/products/23789704-aquaticlife-color-changing-di-resin-cartridges-10-in-3-pack](https://www.desertcart.co/products/23789704-aquaticlife-color-changing-di-resin-cartridges-10-in-3-pack) --- *Product available on Desertcart Colombia* *Store origin: CO* *Last updated: 2026-08-18*
