When to use?
When there is a build-up of nuisance plants such as duckweed. Cristalclear removes phosphate from the water, the nutrient responsible for the rapid spread of duckweed.
Add to the pond every week for the first 2 weeks and every other week thereafter during the growing season.
How to use?
- 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.
