NTLabs Sludgeclear 500ml

500ml treats 2000 gallons once. When to use:

Use when there is a build-up of sludge on the bottom of the pond, use after addition of algae and blanket weed treatments. Sludgeclear is a blend of enzymes and bacteria designed to digest organic material leading to a cleaner pond and filter with fewer opportunities for disease-causing organisms to hide. Sludgeclear supports and encourages the activity of the biological filter bacteria.

Do:

Shake bottle well.
Mix the correct dose in a clean bucket of pond water, then pour evenly around the pond.
Use Sludgeclear regularly during the pond season to help keep your filter and pond clean.

To calculate pond volume -
length (ft) x width (ft) x Depth (ft) x 6.25 = pond volume in gallons.
