NT LABS Pond Cristalclear 500ml (remove duckweed)

Description

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.

NT Labs Cristalclear for duckweed in SG ponds

Duckweed spreads alarmingly fast across Singapore ponds, where warm water and bright sun let a small patch blanket the entire surface in a matter of weeks, blocking light and gas exchange. We stock this Cristalclear because it tackles the root cause by stripping out the phosphate that fuels that explosive growth, which is a more durable approach than endlessly scooping the surface only to watch it return.

For the best outcome, rake off as much floating weed as you physically can before dosing, then apply on the recommended schedule through the growing season, which in our climate is effectively all year. Badly affected ponds can take a doubled dose safely, and the manufacturer notes results build over a sustained period, so treat this as a steady programme rather than a single quick fix.
