Envii Pond Klear - Natural Green Pond Water Treatment, Clears Green and Murky Water for Crystal Clear Healthy Water, Safe for all Fish and Wildlife -1L Treats 40,000 Litres

We're delighted with this product as it is easy to use, the water clarity is so good and our pond appears to have recovered from the awful green colour that it was. We don't have fish so are unable to comment on their health but the pond plants seem to be fine.

So far pretty encouraging. Have treated twice for a bad case of green water. Product info is a bit vague so do some research Tip 1: Don't use tap water for the watering can mix and pouring,use pond water Tip 2: Use mid morning for most favourable p H.

Really great product solidify the mould grown threw sunlight and sinks it leaving clear water

I have used 2 bottles and my pond is still green it hasn't worked

Really easy to use and in 2 weeks my algae bloom is all clear!! I did also include a water Lilly and replaced the UV bulb in my filter so it's been a team effort but pretty sure this product helped get us back to clear water!! It's a small pond so may take longer for larger ones

I am now on week 7 of treatment, but there isn't any improvement at all. It states that it should take between 7 - 8 weeks, but obviously this is not the case. I even covered the pond with netting to keep the extreme heat we are having to protect the water, but to no avail. I even purchased the Pond Equaliser as recommended. Only option is to drain it right out and start again, I suppose

Used 3 treatments seems to be making pond water clear

Excellent

Absolutely no good what so ever used two bottles and the pond is still a green.

Ottimo prodotto ! Fa benissimo il suo lavoro , acqua limpida in pochissimo tempo e sparisce anche odore di acqua stagnante

Räckte inte till min damm men funka så de gröna algerna i vattnet försvann...vattnet var grönt nu är de klarare & inte grönt

Tengo un estanque de unos 400 litros en el exterior. Con tanta luz tuve problemas de diatomeas y después de algas verdes. El estanque llegó un momento que era color “verde bosque”. Los parámetros del agua en rango. Los alguicidas de Acuario nada. Cambiar agua nada. He conseguido volver el agua transparente, que se ven hasta los granitos de arena del fondo con nitidez, combinando este producto con una lámpara UV que he colocado dentro del filtro. La primera semana no hizo aparentemente nada. La siguiente duplique dosis y el milagro apareció. Hay que tener un poco de paciencia.

Pond was VERY green, double dosed after finding UV lamp had blown. Cleaned very green pump filter sponges. Left new UV off for three days after dose, then again seven days later after second dose. Pond was very green, could hardly see fish. Two weeks and really noticed a difference, three weeks and totally clear.
