Tetra CrystalWater is a liquid water clarifier designed to remove cloudiness from freshwater aquariums. Its active ingredients bind fine suspended dirt particles into larger clusters that can be captured by the aquarium filter, helping restore clear water. It works against cloudiness caused by fine substrate particles, food residues, fish waste, and decaying plant matter. Initial results are usually visible within a few hours, with crystal-clear water typically achieved within 6–12 hours. The formula is suitable for freshwater fish and aquatic plants but must not be used in aquariums containing invertebrates such as shrimp, snails, or other crustaceans.
**Directions for Use:** Shake well before use. Add 5 mL per 10 L of aquarium water. If the carbonate hardness (KH) is 3°dH or lower, use 2.5 mL per 10 L instead. Wait at least 48 hours between applications and keep the aquarium filter running to remove the bound particles. Wait 24 hours after using CrystalWater before adding a water conditioner such as Tetra AquaSafe.
**Size:** 250 mL
**Suitable for:** Freshwater aquariums containing fish and aquatic plants. Not suitable for aquariums with invertebrates.
