Tetra CrystalWater, 500 ml

Looking to give your aquarium a boost?
With CrystalWater from Tetra, you can transform cloudy water into a crystal-clear underwater landscape in no time, making your fish and plants truly stand out! This water clarifier works reliably and is gentle on your aquarium inhabitants, using specialised minerals to target murkiness. These active ingredients bind fine suspended particles—the cause of unsightly cloudiness—into larger clumps, allowing your filter to easily trap and remove them from the water.

You will notice the first positive changes after just two to three hours, and within six to twelve hours, you can enjoy a perfectly clear view of your freshwater tank. It is the ideal solution for achieving aesthetic purity quickly without compromising the biological balance of your setup.

Please Note:
This product is not suitable for aquariums containing invertebrates, such as shrimp, crayfish, or snails.

Application & Dosage:

• For best results, add 5 ml of CrystalWater per 10 litres of aquarium water.
• If your KH (carbonate hardness) is at or below 3 °dH, please halve the dosage to 2.5 ml per 10 litres.
• Always wait at least 48 hours between applications.
• If you are also using a water conditioner like Tetra AquaSafe, please wait 24 hours after adding CrystalWater before applying the conditioner.
