Envii Pond Klear Xtra – Strong Pond Clear Water Treatment, Naturally Clears Green Pond Water – Treats Up To 100,000 litres

Excellent item, does the job.

I have to say I didn't think this would work but it did eventually! I have quite a large pond which was thick green and i'd given up trying different things to fix it. I find calculating the amount of pond water and then the amount of treatment required quite difficult. I cleaned the pump and filters and added about a third of the bottle to a watering can and added to the pond. I then cleaned the pond filters every couple of days. I did this three times in total from one bottle of treatment and the water is now considerably clearer. My biggest bugbear with these bottles is the dosage contraption. I don't find it helpful at all in calculating how much you need. It also make it really difficult to get the stuff out of the bottle. I end up cutting the top off the bottle. Maybe that is easier for smaller ponds but I need to use quite a lot of treatment. Overall it worked for me but ponds still seem to be a bit hit and miss. I inherited mine with the house so i'm still figuring it out!

My wife and myself are so pleased with this email pond cleaner The first Friday I put in the mix as described on container but added 20 mil more in 5 Lt Of pond water. Two days after it started to clear, the second Friday I added the correct amounts Cleaning the filters at the same time. By Sunday morning the water is clear and clean And now happy fish. Before it was like pea soup and slimy 60 Lt pond Plenty more for the summer months

I have a pond of 23000 litres now on second bottle, on my 4th week with very little effect, I will keep trying but loosing confidence that this will work for me.

arrived on time excellent product

I have bought and used this product and I am totally disappointed with it. I used it in two different water features and it has not cleared the green algae at all! I used it first with just the recommended dose for about 200liters of water and nothing happened and then I poured the rest of the whole bottle in one water feature and again the green algae were not cleared. I used other products and they at least are clearing the algae in my water feature for about two weeks before I. Red some more. Thoroughly disappointing is this product and can’t recommend at all! Sorry! Zero stars if at all possible!

Used this over a few weeks it worked ! Can now see my fish

Used all doesnt seem to make a difference

Green water. Followed instructions to the letter. Gave triple dose at start. Partially exchanged water three times. After 5 weeks the pond is just as green

Rende l’acqua cristallina

Het schijnt nogal een tijd te duren voordat het werkt, 6 tot 8 weken las ik. Dus ik kan er nog niets zinnigs over zeggen. We zijn nu ongeveer twee weken verder en het is nog steeds behoorlijk groen. Dus 3 sterren vanwege de onzekerheid of het wel gaat werken.

como ayuda es un buen producto,pero no es todo lo que requiere un estanque para estar transparente 100%, además que tampoco es inmediato, hasta la tercera aplicación no he apreciado mucho cambio, pero después sí que se nota mucho. A parte, quita el verde (algas monocelulares en suspensión ) pero nada más. lo que también es bueno decir es que he seguido la dosificación escrupulosamente y no ha muerto ni un solo pez y ninguna rana de los varios decenas que tengo (alguno más de 100 en cuanto a peces y varias decenas de ranas ). no duraría en volver a comprarlo si se me vuelve a poner el agua verde con el sol.

A éviter absolument. Tous mes poissons sont morts et pourtant j'ai fais ce qu'il fallait (bien lu et appliqué comme ecrit) mais hélas.........sniff !!! Beaucoup de peine pour ces pauvres poissons.
