Filled it with well water and let the water pump circulate without fish for 30 days. While the tank is in-ground, it was open air at the point of filling. In about a week.. It was so green that I could only see about 6 inches into it. Did some research.. Found this product. Added 24 ounces (shake the bottle WELL!) In 4 days.. The water was literally crystal clear! Have since added 10 small koi (approx 2 pounds of fish) and they have been thriving and growing for 8 weeks now. Have added the clarifier 2 more times at 3 week intervals (16 ounces each time) and the water as remained crystal clear. One week ago added 4 small (4 inch inch) algae eaters.. Will be keeping the clarifier handy in case they can't keep up with the algae produced by being in only partially shaded from the high Florida sun. VERY SATISFIED! Review: Works amazingly - Haven't used just a ton of products but don't plan on using anything else because this works wonderfully. Water clarity is impressive and fast. ## Features - Clears Pond Water With Natural Microbes -- CrystalClear OneFix quickly balances ponds and improves water clarity by utilizing natural microorganisms that consume and eliminate suspended dead organics. - Fast-Acting Formula -- Starts working the second it hits the water.

Use 1 fluid oz per 375 gallons every 2 weeks. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | CrystalClear | | Item Form | Liquid | | Item Weight | 1.2 pounds | | Liquid Volume | 1 gallons | | Manufacturer | Airmax | | Pet Type | Fish | | Target Species | Fish | ## Product Details - **Brand:** CrystalClear - **Item Form:** Liquid - **Item Weight:** 1.21 Pounds - **Liquid Volume:** 1 Gallons - **Manufacturer:** Airmax ## Images ![CrystalClear OneFix - Natural Water Clarifier - 1 Gallon Treats up to 48,000 ... - Image 1](https://m.media-amazon.com/images/I/71idNjr6FDL.jpg) ![CrystalClear OneFix - Natural Water Clarifier - 1 Gallon Treats up to 48,000 ... - Image 2](https://m.media-amazon.com/images/I/81uB-SnwMQL.jpg) ![CrystalClear OneFix - Natural Water Clarifier - 1 Gallon Treats up to 48,000 ... - Image 3](https://m.media-amazon.com/images/I/71MxVLYlfqL.jpg) ![CrystalClear OneFix - Natural Water Clarifier - 1 Gallon Treats up to 48,000 ... - Image 4](https://m.media-amazon.com/images/I/91epFKGcYML.jpg) ![CrystalClear OneFix - Natural Water Clarifier - 1 Gallon Treats up to 48,000 ... - Image 5](https://m.media-amazon.com/images/I/81xv75bNyIL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ VERY SATISFIED!! *by J***. on July 20, 2019* Have a 3000 gallon tank I set up for raising koi (engine for an aquaponic system.)
