envii Sludge Klear Pond Sludge Remover, Natural Bacteria Sludge Buster Digests & Controls Organic Waste, Safe for All Fish & Wildlife Treats Up To 60,000 Litres (13,200 Gallons)

Absolutely excellent. I've tried various treatments, but this is the best. I double dosed the first application and the pond cleared in 3 days. It's the first time I've seen the bottom of the pond in a year. Thank you Envii sludge clear.

We have a 2,800 litre pond which is stocked with goldfish. It has never been emptied since we filled it 7 years ago! We now have a small in-pond filter with UV and this has killed off a lot of algae, making the pond water somewhat clearer. We use Sludge Klear to lift dead leaves and remove dead algae. It clumps together the algae in large ‘bergs’, also bringing semi rotted leaves to the surface. You can then lift these off with a fine mesh net (which dead algae doesn’t fall through if you remove it carefully). Initially the water is cloudier but after a few days (and remival of a few bergs, the water clears a bit. We are doing this weekly at present, in the expectation that the water will gradually clear. This is not a product that achieves a fast result but neither does it damage fish (or any other creature’s) health.

Used one tablet in my pond just a week ago and it's looking much better. Very happy with my purchase.

The sludge clear definitely helps control algae production, and while there is a visible improvement I found it did take more than what was recommended so glad I over ordered. As for it’s effectiveness, do manage your expectations as it wont in of itself create perfect crystal water. You still need to control and remove debris.

For as many years as I can recall our well stocked fish pond has turned green in Spring and we haven't seen a fish until almost Autumn. We've tried planting (much to the delight of our grass carp), as many chemical remedies to reduce the algal bloom as there are on the market and traditional barley hay. It's safe to say that we have never known what eventually gets on top of the problem, it just clears one day. This year however is different. We introduced your product in early April during which, luckily for us, there was a really cold spell which, presumably, delayed the onset of our annual algal bloom problem. The product states that it works at cold temperatures but nevertheless given our 10 year experience of green water and the multiple products used I must say not much success was anticipated. I'm delighted to state that I was completely wrong. I followed up with a second dose a week later and at about one month from dose one I've added a third. We're now mid May and the pond is delightfully clear despite the warmer weather and long daylight hours. We no longer have to wait until feeding time for a glimpse of a fish mouth! Further, the slurry I remove from the filter box no longer sends a whiffy bad eggs aroma up my nose when I lift the lid and I suppose this is a further effect of the product.

I don't have time to review all items. They're ALL work exactly how they suppose to. Good value for money

ALL GOOD THANK YOU

This awful stuff has killed my lovely goldfish within a couple of days of putting it into my pond. I spoke to my local Aquatic shopkeeper and it seems the sludge remover also removes hugh amounts of oxygen from the water, and the shock of this can easily kill your fish. I'm so upset. I've had the fish for years and now I've killed them thinking I was doing the best for them by using this horrible product.

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.

Reicht ist schön sauber geworden

Funciona bastante bien en la eliminación de lodo. Pero no hace milagros si alguien se lo espera.

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

usage compliqué mais éfficace sur la boue
