Safety Precautions for Freshwater Aquariums (Core Fundamentals, Mandatory Compliance) 1. Strict Dosage Control, No Overdosing: Use 50g per 100L of water for mild yellow water, and 100g per 100L for severe yellow water. Overdosing can rapidly alter the ion balance of the water, causing a sudden rise or drop in pH and leading to stress or death in fish and shrimp.\u003cbr\u003e2. Timely Removal to Prevent Water Quality Fluctuations: Remove the protein cotton immediately after the water clears (within 1–3 days) and do not leave it soaked in the aquarium for a long time. Once saturated, protein cotton will release adsorbed substances in reverse and continuously alter water pH, resulting in significant pH fluctuations and damage to the nitrification system.\u003cbr\u003e3. Isolate from Agents, No Coexistence in the Aquarium: Remove the protein cotton immediately before adding any chemicals (fish medicine, bactericides, algae removers, etc.) to the aquarium. The strong adsorptivity of protein cotton will absorb all chemicals, rendering them completely ineffective. Additionally, adsorbed chemicals will adhere to the cotton and may be residual and released after regeneration, causing secondary water pollution.\u003cbr\u003e4. Pretreat New Cotton to Prevent Dye Leaching and Turbidity: Rinse and knead new protein cotton repeatedly with clean water until the effluent is clear before use. This prevents floating dyes and powder from the cotton from entering the aquarium, which would cloud the water, impede fish and shrimp respiration, and avoid the nitrification system having to decompose the dyes, increasing the water body's load.\u003cbr\u003e5. Avoid Use During Nitrification System Establishment: Do not use protein cotton when the nitrification system of a newly set up aquarium is unstable. The aquatic ecosystem is fragile at this stage, and the pH-regulating effect of protein cotton will directly inhibit the reproduction of nitrifying bacteria, leading to nitrification system collapse and excessive ammonia and nitrite levels.\u003cbr\u003e\u003cbr\u003eII. Safety Precautions for Seawater Aquariums (High Risk, Critical Warnings) 1. Strictly Forbidden for Non-Professionals: Protein cotton strongly adsorbs core indicator substances in seawater aquariums such , magnesium, KH, and trace elements, rapidly disrupting the seawater's ion balance, hardness, and alkalinity. Marine organisms (corals, sea anemones, shellfish, marine fish) have extremely low tolerance to ion and pH changes—even minor fluctuations can cause large-scale mortality. Only professional aquarists may use it with precise water quality monitoring, strict dosage control, and short-term application; it is absolutely forbidden for beginners. 2. Extreme Timing and Dosage Control for Professional Use: For professional operation, the dosage must be far lower than the freshwater standard. Real-time monitoring of seawater pH, KH, calcium, and magnesium levels is required. Remove the protein cotton immediately after water clarity improves, with the total usage time not exceeding 24 hours to avoid a catastrophic drop in water parameters.\u003cbr\u003e\u003cbr\u003e3. Do Not Reuse After Regeneration for Seawater Use: If protein cotton has to be used in a seawater aquarium, it must not be reused in seawater systems. Even after regeneration with concentrated salt water and rinsing with clean water, the adsorbed marine trace elements cannot be completely removed, and their rapid release upon reuse will damage water quality.  III. Safety Precautions for Regeneration Operations (Avoid Cotton Invalidation and Secondary Water Pollution)\u003cbr\u003e1. Regenerate After Saturation, Do Not Force Continued Use: Remove and regenerate protein cotton promptly after it becomes saturated (when water clarity no longer improves or even reverts to yellow). Do not continue soaking it, as it will release pollutants in reverse and contaminate the water.\u003cbr\u003e2. Use Concentrated Salt Water for Regeneration, Strictly Control Soaking Time: Soak the cotton in high-concentration salt water (recommended sea salt\/table salt with a concentration of approximately 10%–15%) for 4–12 hours. Insufficient soaking time will prevent complete desorption of adsorbed substances, leading to incomplete regeneration; excessive soaking time will corrode the cotton and reduce its subsequent adsorption efficiency.\u003cbr\u003e3. Thoroughly Rinse After Regeneration to Eliminate Salt Residues: After soaking in concentrated salt water, rinse and knead the cotton repeatedly with clean water until the effluent is free of saltiness and foam. This prevents salt water from being introduced into the aquarium, which would cause a sudden rise in water salinity, leading to osmotic imbalance and death in fish and shrimp (freshwater fish are particularly sensitive to salinity changes).\u003cbr\u003e4. Store Regenerated Cotton Separately to Prevent Contamination: Air-dry regenerated protein cotton and store it in a dry, odor-free, and chemical-free environment. This avoids adsorption of airborne impurities and odors, which would contaminate the aquarium upon reuse.\u003cbr\u003e\u003cbr\u003eOther General Safety Details\u003cbr\u003eAvoid Simultaneous Use with Other Adsorbents: Do not use protein cotton with other adsorptive products such as activated carbon or ammonia-removing stones. The combined use of multiple adsorbents will accelerate changes in the physical and chemical indicators of the water, causing dual fluctuations in pH and ion balance and increasing water quality risks.\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003cp style=\"text-align:left;margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px\" align=\"left\"\u003e\u003cimg style=\"width:800px;height:800px\" width=\"800px\" height=\"800px\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sc86879948f284370ad3a9b143d64b9c5u.jpg?width=800\u0026amp;height=800\u0026amp;hash=1600\" slate-data-type=\"image\"\u003e\u003cimg style=\"width:800px;height:800px\" width=\"800px\" height=\"800px\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Se5e8f69f58b042f28903ef2c9721b2b5Y.jpg?width=800\u0026amp;height=800\u0026amp;hash=1600\" slate-data-type=\"image\"\u003e\u003cimg style=\"width:800px;height:800px\" width=\"800px\" height=\"800px\" src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S1a6c587794314bdbab86971562a9b845H.jpg?width=800\u0026amp;height=800\u0026amp;hash=1600\" slate-data-type=\"image\"\u003e\u003c\/p\u003e\n\u003cp style=\"margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;display:block;width:100%\"\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sa0f0118eedf44468881a23cd37ff1c85a.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S56f1d29da0324427857583489a8bef52X.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sf555f800b937460a8abe155f3dd45534Z.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S6068c79ef9eb4eb1bb1092c49b54aab5O.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/S28cb32ce83f448db951948ea2aa61412m.jpg\" slate-data-type=\"image\"\u003e\u003cimg src=\"https:\/\/ae-pic-a1.aliexpress-media.com\/kf\/Sf25da4fe7aab4fbbb64f5f27d880d98b9.jpg?width=800\u0026amp;height=800\u0026amp;hash=1600\" slate-data-type=\"image\"\u003e\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Aquaphoria","offers":[{"title":"400g","offer_id":47158476374063,"sku":"1005012094690935-400g","price":46.99,"currency_code":"USD","in_stock":true},{"title":"200g","offer_id":47158476406831,"sku":"1005012094690935-200g","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0771\/4655\/4415\/files\/Sa0f0118eedf44468881a23cd37ff1c85a_7caa9238-d60c-4615-900f-173abf67eb56.webp?v=1794425093","url":"https:\/\/aquaphoria.shop\/products\/aquarium-filter-resin-fish-tank-water-purification-filter-media-remove-yellow-water-deodorization-resin-filter-cotton","provider":"Aquaphoria","version":"1.0","type":"link"}
