## Overview

Envii Sludge Klear is a natural, bacteria-powered pond treatment designed to digest sludge and organic waste safely and effectively. Each tablet contains 100 billion beneficial bacteria, treating up to 5,000 litres, with a full pack covering 60,000 litres. Its patented low-temperature bacteria work year-round, even in cold conditions down to 40°F, making it ideal for maintaining clear, healthy ponds without harming fish, wildlife, or plants.

## Description

Envii Sludge Klear is safe for pets, works in all ponds and is 100% natural All ponds will, at some point develop a layer of sludge at the bottom that will fight for oxygen in the water, depriving the good bacteria and algae. Envii Sludge Klear removes that sludge build 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. With patented low temperature bacteria, Sludge Klear can be used all year round and down to temperatures as low as 40?. 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. How To Use:Clean out filters prior to using Sludge KlearTurn off UV light for 3 days during treatmentRemove any surface algae where possibleUse 1 tablet per 1,250 gallons of pond water, add to bucket of pond water, stir and leave for a minimum of 2 hours for best resultsStir again prior to distributing evenly over pond surfaceFor initial use, we recommend an initial double or triple dose and then treatment every 5-7 daysBadly affected ponds may benefit from higher dose levels until effect on water visible. 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.

Review: Patience - Au début il a provoqué un gros verdissement de l'eau mais après quelques jours l'eau est devenue transparente et la vase disparaît progressivement
Review: Hoeveelheid slib is belangrijk - 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.
