envii Sludge Klear Pond Sludge Remover, Natural Bacteria Sludge Buster Digests & Controls Organic Waste, Safe for All Fish & Wildlife, 6 Tablets treats 30,000 litres

Worked brilliantly. Pond before was basically black. Now it is clear! Awesome. First 2 photos are before. Last 2 photos are after.

Product seems very good delivery took a long time

Keeps the sludge away and keeps the filter clean as well

At first you will wonder if you wasted your money, but this product does work. I started my application 6 weeks ago & only just started seeing the results.

pretty sure it worked but then the pond filters kept getting blocked so wether it actually broke down the sludge is hard to tell

It was as "described on the tin" however the product did not solve my pond problem. This is no fault of the supplier but a really hot summer making more algae

Extra large pkt of pond clearing tabs simple instructions to clear pond water of sludge by tablets with enzymes ,so far they are doing as described clearing up. My pond water,now several months of use seems to also reduced the dreaded pond weed

Very clever marketing for products that don’t work. You buy their pond clear and that causes more algae to grow. You buy their algae product and then you need the sludge clear. It goes on! I don’t rate them at all.

Très efficace

Schade das es nicht mehr Lieferbar ist! War sehr gut

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.

Excelente para eliminar el agua turbia de los estanques Para las algas(verdes) existen otros productos de la misma compañía muy eficaces

Ottimo prodotto da quanto ho iniziato ad usarlo mai più viste alghe nel laghetto. Nessun problema per pesco, piante. Prodotto acquistato da almeno 3 anni
