## Long description

Tetra CrystalWater 250 ml is a liquid water clarifier formulated for freshwater aquaria. The solution binds fine suspended particles and microscopic debris into larger flocs that can be removed by filtration or will settle, restoring water transparency after substrate agitation, plant maintenance or stocking changes. It is intended to be used as part of routine aquarium care to improve visual clarity while remaining compatible with common fish and aquatic plants when used according to label directions.
Advantages
Tetra CrystalWater quickly reduces cloudiness by coagulating tiny particles without changing water chemistry when dosed as instructed. The ready-to-use liquid is easy to measure and add to the aquarium, works alongside mechanical filtration, and helps maintain a clearer viewing environment for observation and aquascape enjoyment. The formulation is designed for freshwater systems and is suitable for repeated use following recommended intervals.
Suitable for
Freshwater community aquariums with mechanical or biological filtration
Aquaria after substrate disturbance such as cleaning, gravel rinsing or rearranging décor
Following heavy plant trimming or introduction of new substrate that stirs up debris
During routine maintenance to speed up clarification between water changes
When it may not be suitable
This product is formulated specifically for freshwater aquaria and is not intended for marine or brackish systems. It is not a substitute for biological filtration or chemical water treatment aimed at altering pH, removing dissolved toxins or treating disease. In cases of severe long-term turbidity caused by algae blooms, organic overload or water quality failure, addressing the root cause and performing water changes and filtration maintenance are required.
Key specifications
Form: ready-to-use aqueous liquid
Volume: 250 ml
Application: binds suspended particles to form larger flocs for filtration or settling
Target aquaria: freshwater systems
Compatibility: safe for fish and live plants when used according to directions
How to use
Measure the recommended dose according to aquarium volume and add directly to the water, dispersing gently across the surface.

Monitor filtration performance and remove visible floc using a net or by increasing mechanical filtration if necessary. Follow the manufacturer’s dosing frequency and wait times between repeated treatments to avoid overuse.

Product is intended for freshwater aquaria only
Not a replacement for proper filtration, water changes or biological maintenance
Follow dosing instructions to ensure compatibility with fish and plants
Usage recommendations
Use after physical disturbances such as gravel cleaning, plant trimming or decor rearrangement to restore clarity. Combine with routine filter maintenance and partial water changes for best results. Avoid repeated consecutive doses unless indicated on the product label.
