About this item
- 【 CONTROLS DUCKWEED】: Controls the unsightly spread of duckweed in pond water by reducing its natural food source.
- 【REMOVES PHOSPHATE】Cristalclear removes phosphate from the water, the nutrient responsible for the rapid spread of duckweed.
- 【USE THROUGHOUT THE POND SEASON TO TARGET DUCKWEED】Add to the pond every week for the first 2 weeks and every other week thereafter during the growing season.
- 【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. Shake well before use. For best results, rake off as much duckweed as possible first. Mix full dose in a clean bucket of pond water, and then pour evenly around the pond. If the water is very badly affected the dose can safely be doubled without risk to fish. Use for a minimum of 6 months to achieve the optimum benefits.
- 【 SUITABLE FOR ALL POND KEEPERS 】: Pond Cristalclear’s ease of use means it is perfect for use by beginners and seasoned pond keepers alike. This product is wildlife and pet safe.

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.
