About this item
  • Rapid Cleaning: Crystal by Hydra is a cleaner that rapidly acts as a pond treatment for green water to give crystal clear water. This algaecide contains powerful detergents and sequestrants that rapidly dissolve and solubilize outdoor contamination.
  • Safe to Use: Special green water treatment formula improves the water quality without disturbing the ecological balance of the pond. Immediately after the product application, scattered single-celled algae flocculate will clump together to be removed through the filter system.
  • Environment friendly: Crystal is a biodegradable green water treatment that is save for fish, reptiles, birds, invertebrates, mammals, humans, and water plants. Also, it is not harmful for biological filters or pumps installed in the pond.
  • Multipurpose: Hydra Crystal is the pond treatment that has no damaging effect on concrete surfaces or synthetic liners. It has a shelf life 3 years and 3 Kg pack can treat up to 30,000 litres of water.
  • Customer Satisfaction: The satisfaction of our customers is our priority. In case of any query related to the Hydra Crystal, feel free to contact us. We will be at your service and try to provide an answer as soon as possible.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
