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

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

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!

I inherited a pond when I moved house that hadn't been maintained in 15 years! Boy, what a mess! 2 feet of sludge and and 20,000 litres of thick water. I was loathed to put my koi into this muck but had no choice. So the battle began in April of this year when I bought the first lot of Pond Klear Extra which failed miserably. I had some excellent help from Andy Hiron at Bio8 who responded to my emails almost instantly each time. Thank you, Andy. I had introduced some plants to the pond which in turn introduced an abundance of parasites and lost 50% of my stock, including my prized koi. Note to self....thoroughly wash all oxygenating plant "before" adding to the pond! Pond treated, happy healthy fish, water tested and stable, now onto water clarity.Last weekDay 1 - Cleaned filters and removed UV bulbs. Carried out a 30% water change. Added Envii Sludge KlearDay 2 - added Envii Pond KlearDay 4 - water born algae build up but the water itself appeared clearer?. Cleaned filters and replaced UV BulbDay 5 - the water is definitely clearer!Day 6 - are my eyes deceiving me! Are they fish I can see????Day 7 - WOW! I can see at least 3 feet down and all of my fish, including some Rudd which I didn't even know I had!If the ponds stays at the current level of clarity I will be extremely happy. But I have a feeling that I will be able to see the bottom which is 5 feet in some places over the next few days. To say I am pleased is an understatement. Hopefully you can see the difference in the attached photos. One before Pond Klear and two taken today, day 7. I've tried so many products in the past but won't be now. This is my recipe for success!!Update July 21. Pond crystal clear! Envii sludge klear is also amazing. I can see patches if white gravel that I didn't know was there!

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.

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

I have waited over a year to review this product as I have waited for all permutations on my pond to play out.I have had a 5000 gallon ponds for several years and various pond before that. I have never had a problem with clarity or chemistry. PH always about 7.2. The pond is stocked with Koi and goldfish. I have a three bay filter with brushes, Alfagrog and foam. In addition I have a veg filter and 55 Watt Uv filter.Last year, my pond was not as clear as usual. A slight cloudiness and a definite 'tea' colour developing. Dissolved organic compounds I thought. The Envii product looked ideal.I added the bottle of Envii Pond Klear Xtra as directed and waited. I was amazed that all the 'dirt' in the filters disappeared within a day or so. However, the pond was no better and got more cloudy. The pond became murkier and I was starting to get problems with PH, ammonia and nitrite. PH was always 8.3 or higher, ammonia and nitrite was appearing in testing. I contacted the company who suggested a PH buffer product. My GH and KH levels were fine, so adding another expensive product did not seem a good idea.Before the Envii product was added, I would clean my brush bay every few weeks; always full of dead algae. Not any more. Nothing in it. UV filter all good. A jar test suggest no algae problem, but PH and chemistry are not good. It's as if my old filter bacteria has been turned off and replaced with something different.Since then I have added various potions, done loads of water changes, but nothing has improved. I can get passable nitrite and ammonia results by drastically cutting food and I can get some clarity by constantly adding fine fleece filter material to the last bay.I cannot prove in any way that the Evii product has caused problems, simply report my findings. However, I wish I had never used the product.

Easy to use, very safe, very durable,

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.
