## Description

Envii Sludge Klear is a pond water treatment that removes the sludge that builds up in ponds.Task-specific bacteria break down the sludge that sticks to your pond, digesting and loosening it to enable the filter to catch it.Envii Sludge Klear can be used all year round with patented low temperature bacteria. This allows for treatment in winter to reduce the effect of green water in spring. With 100 billion bacteria per tablet, Sludge Klear can be used to solve sludge problems or as a regular treatment for protection and because it is safe for fish, it's perfect for use in garden and Koi ponds. It also works as a biological filter starter for ponds by helping create the perfect biological balance in your filter. Simply dilute a tablet in a bucket of pond water for 2 hours, switch off the pump for 1-2 hours and add the contents of the bucket to your filter to allow them to colonise the filter media without being washed through, then turn your pump back on. Features & Benefits - Specifically targets pond sludge - Biological filter starter for ponds - 1 pack of 6 tablets treats 30,000 Litres - UNIQUE - Works as low as 4°C - All Year Treatment - Completely Safe for Fish - 100% Natural For badly affected or natural ponds with no filter system, use a double or triple dose to increase the bacterial numbers to cope with increased levels of sludge.For more information don't hesitate to call us on +44 (0)1246 240880 or visit our website.

Review: Voor een vijver van 30.000 liter en om zeker te zijn dat ik de bodem terug zou zien, heb ik de gehele verpakking opgelost volgens de gebruiksaanwijzing. Zelfs meer dan twee uur laten staan alvorens toe te voegen aan de vijver. Echter zonder resultaat. Ik vermoed dat er bij mij gewoonweg teveel slib in de vijver aanwezig is en dat ook nog is een natuur filter heb. Dat is dan ook waarom ik 3 sterren geef. Ik kan niet zeggen of het nu een top product is of niet omdat ik gewoon weg niet weet bij wie het probleem ligt.
