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

Use it for a small pond with goldie, frogs and other creatures . Works really for well for a little pond Good quality water . Nice , clear and clean. Bigger scale ? No idea.

Expensive and took so long to clear our big pond but got there in the end

This is good stuff and in my 2000 gallon koi pond it worked well. The pond was a sickly green and it is now much better. However you have to stick with it and be generous with the amount used . It says weekly , but I introduced a dose every 4 days. I was also very generous with the dosage. I probably overdosed, but it has not resulted in any problem with my fish and the pond does look clearer. I will probably use it regularly over the summer to keep the green water down

Hasn’t worked at present…. Will attempt another go at the pond this weekend.

This was a reorder of a product I find useful to control green water. Delivered quickly. Reasonable price.

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!

Didn't work for me, and I followed all instructions on the bottle to the letter. After I used up the entire bottle, I received an email from the company selling this product instructing me as to the steps to take to make sure this product works on my pond and before any negative feedback is left. Here is the first step in their email: Before using any bacterial pond product, check your water parameters – the pH level should be below 8.5 and a KH level above 5 – If they are outside of this range, buy Envii Pond Equaliser to immediately buffer water and eliminate toxic heavy metals & ammonia to improve the health of your fish. In essence, they are suggesting that, in order to make this product work, I need to buy another one of their products, which I am obviously not going to do now. When they are selling this product, the description doesn't tell prospective customers that they shouldn't buy it unless their water pH level is below 8.5 and KH level is above 5 because it's not going to be effective. So you have been warned: if your water falls outside of the above range, the suggestion is to buy Pond Equaliser from this company first because otherwise Pond Klear Xtra is not going to be effective. I am not going to do that. I've wasted enough money on two of their products already: I tried Pond Klear and now Pond Klear Xtra. Both are equally useless. Called a local pond specialist. He recommended a good quality bacterial product that costs more than this one but cleared our pond quickly and without any additional purchases.

Did not do much in my pond.Used whole container over 2 weeks in my 4000 gallon pond with very little difference to the Green water,

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

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.

Ho un laghetto piccolo (3x2 m circa 1,0-0,5 m profonditi con le piante e molti pesci. Inverno si è rotto sia aspiravano sia il tubo UV lampada dentro filtro e prima che mi ero accorta con i primi caldi di marzo-aprile l'acqua è diventata verde e neanche tanto un po di aggiunta acqua fresca che aiutava. oltre di tante fango accumulato sullo sfondo. Al inizio ho aggiunto la quantità normale indicata per trattamento, ma non vedendo i resultati dopo qualche giorno ho aggiunto ancora stessa quantità o forse anche di piu (poi che ho letto che se lo stagno è sporco molto la quantità può essere raddoppiata). anche se sapevo che l'effetto non arriva subito, comunque non vedevo tanto differenza neanche dopo 1,5 settimane. Avevo perso la speranza quando improvvisamente circa dopo 2 -2,5 settimane l'acqua ha iniziato pian piano diventare sempre più limpida e lo sfondo piu pulito e quanto sembra fin adesso questo effetto è duraturo (e ancora non ho comprato il nuovo filtro UV, cioè l'effetto è senza nessun altro trattamento d'acqua). Funziona benissimo, i pesci sono sani e contenti e anche noi che finalmente li possiamo vedere. mai visto lo sfondo del laghetto cosi bene anche con filtro UV e pulendo sempre con aspiravano.

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.
