Seachem Clarity 100 mL – Aquarium Water Clarifier

Seachem Clarity 100 mL is an aquarium water clarifier for freshwater and saltwater aquariums with cloudy, hazy, or dusty water. It is commonly used after substrate disturbance, new tank setup, maintenance, or when fine particles are suspended in the water column.

Clarity works by helping fine suspended particles bind together so they can be removed through mechanical filtration. For best results, use with proper filter media and follow the Seachem product label for dosage and treatment instructions.

Key Features

  • Use With Testing & Filtration: Works best alongside proper aquarium maintenance and filtration

How to Use

Use Seachem Clarity according to the product label. Dose the correct amount based on aquarium volume and keep mechanical filtration running so particles can be collected and removed.

Clean or replace mechanical filter media as needed after use, since trapped particles can reduce filter flow. Follow manufacturer instructions regarding UV sterilizers, ozone, and repeat dosing.

Cloudy Water Tips

  • Identify the likely cause of the cloudiness before treating
  • Make sure mechanical filtration is running properly
  • Rinse dusty substrate before adding it to a new aquarium
  • Avoid overfeeding, which can contribute to water quality problems
  • Test ammonia, nitrite, nitrate, and pH if water appears cloudy
  • Clean mechanical filter media as needed after clarifier use
  • Do not rely on clarifiers as a replacement for water changes and filtration maintenance

Important Aquarium Care Note

Cloudy water can be caused by several issues, including substrate dust, bacterial blooms, excess food, high organic waste, disturbed decorations, or filtration problems. A water clarifier may help with suspended particles, but it does not replace water testing, proper filtration, tank cycling, or routine maintenance.

If cloudy water is caused by ammonia, nitrite, overstocking, or a new uncycled aquarium, address the underlying water quality issue in addition to using any clarifying product.
