About this item
  • 【WATER POLISH】: Mediclay stimulates the biological system in favour of beneficial bacteria helping to reduce algae. Mediclay will also “polish” the water resulting in amazing clarity to observe your fish. Use as a weekly additive to re-mineralise pond water to control the build up of organic waste, bacteria and pollutants which cause bacterial infections and ill health.
  • 【MONTMORILLONITE CLAY】: Mediclay is a high-purity montmorillonite clay containing a variety of minerals and trace elements which are beneficial to fish health and water quality and clarity. Montmorillonite clays are produced by the weathering of volcanic ash, and are hence high in minerals.
  • 【EASY TO USE】: To work out the required dosage for your pond, simply calculate the volume of your pond in litres (length x width x depth (in cm)/1000) or alternatively, use our Online Dosage Calculator. Mix the required dose in a clean bucket/watering can of pond water then pour over the surface of the pond or at a filter outlet to ensure an even spread. For clarifying the water, Mediclay is best applied via the pump or venturi so that it is rapidly mixed with the water returning to the pond. Use in conjunction with other NT Labs water treatments but leave 48 hours after using an NT Labs Medication before applying Mediclay.
  • 【SAFE FOR USE WITH OTHER NT LABS KOI CARE PRODUCTS】: Use in conjunction with other NT Labs water treatments but leave 48 hours after using an NT Labs Medication before applying Mediclay.
  • 【SAFE FOR USE ALL YEAR ROUND】: Mediclay can be used at any time of year (water temperature) and will not alter the water pH.

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.
