Aquarium Water Softener Resin 500ml, GH KH Reducer for Freshwater & Marine Tanks, Ion Exchange Filter Media to Lower Hardness for Shrimp, Betta, Discus, Tropical Fish

• Scientifically Lowers GH & KH for Sensitive Aquatic Life---This ion exchange resin is engineered to safely and effectively reduce General Hardness (GH) and Carbonate Hardness (KH) by removing calcium and ions. It creates the stable, soft water conditions crucial for the health, breeding, and vibrant colours of sensitive species like Caridina/Cherry Shrimp, Betta Fish, Discus, and many Tetras.
• Versatile 500ml Bag for Freshwater & Marine Applications---A high-capacity 500ml bag of premium resin, suitable for both freshwater and saltwater aquarium filters. It helps replicate natural soft water habitats, promotes better fish gill function, reduces stress, and supports overall ecosystem balance in your tank, leading to healthier and more active aquatic life.
• Easy to Use in Any Filter System for Clear, Soft Water---For best results, place the resin in a fine mesh media bag (suggested) or directly into a dedicated chamber of your canister, hang-on-back, or sump filter. It works alongside mechanical and biological filtration to clarify water and steadily maintain desired softness, requiring only periodic monitoring of hardness levels.
• An Essential Tool for Advanced Aquascaping & Breeders---Achieve and maintain the precise water parameters demanded in competitive aquascaping, crystal shrimp breeding, or delicate fish rearing. This resin gives you direct control over your water chemistry, acting as a foundational tool for creating a thriving, customised aquatic environment tailored to your tank's inhabitants.
• Reusable & Economical with Easy Regeneration Instructions---Unlike disposable cartridges, this resin is rechargeable! When exhausted, simply regenerate it using a common salt (NaCl) solution as per our included guide. This process restores its ion-exchange capacity, offering exceptional long-term value and making it a cost-effective choice for dedicated hobbyists.

Product description Feature: 1. Water softening resin is a special resin specially used to soften hard water. Through ion exchange technology, the hardness of water is less than 50 mg/L. 2. The soft water resin can effectively soften and adjust the water quality, so that the water in the aquarium can meet better growth requirements. 3. High-quality resin filter material, suitable for a wide range of environments, can be used in seawater and water. 4. It has the three-in- functions of filtration, bacteria enhancement and water purification, stabilizes the water environment, and quickly cultivates nitrifying bacteria. 5. Equipped with a fine mesh filter screen, put the water softening resin together with the filter screen in the filter box to achieve a better water softening effect. Specification: Item Type: Soft Water Resin Material: Resin Product Color: As Pictures Shown Volume: 500ml/ Box Resin Diameter: Approx 1mm /0.04 in Product Weight: Approx. 378.0g Product use: Aquarium filter Principle of resin softening: Resin softening water quality is a water treatment method that uses ion exchange water treatment to make the exchangeable ions in the resin and the aqueous solution produce reversible exchange that meets the quantity rules of other substances, resulting in improved water quality without chemical changes in the structure of the exchanger. In this water treatment method, only cations are involved in the exchange , called cation exchange water treatment; only anions are involved in the exchange , called anion exchange water treatment; both cations and anions are involved in the exchange , called cation and anion exchange water deal with. Due to the difference in the water quality of the water, different types of fish tanks such as fish farming, aquaculture, and coral farming have different requirements for water quality, and the softness and hardness of the water quality need to be adjusted according to actual Directions To use this water softening resin, place it in the filter box of your aquarium filter. The resin will soften the water and improve the growth conditions for your fish.
