Pond Klear - Natural Green Pond Water Treatment, Clears Green and Murky Water for Crystal Clear Healthy Water, Safe for all Fish and Wildlife - Treats Up to 20,000 litres (4,400 Gallons)

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.

very good

It takes time to see results with this product. The scenario which we faced was a 200 litre water feature in which my wife had placed two goldfish, pebbles and some plants from our natural pond. Very soon the water and pebbles were totally green and drastic action was needed. We had a smalll solar pump and filter which was not up to the job and therefore we have installed a budget mains powered combined filter and pump; this aerates the water very well and filters it too.So how has this product performed? Not too well at first and I believe that this was due to the pump and filtration system, which whilst solar powered, had an additional battery powered option, which we used to ensure 8 hours of filtering a day. We persevered and purchased a better pump and whilst this had a UV lamp which is constantly on, the combination of the two is addressing the problem. The method which we use to treat our pond is to remove about 8-10 litres of water from the pond, dose it with 25ml of the agent, stir it well and then leave it to develop for 24 hours before introducing it to the main pond whilst the pump and filter is switched off - we leave it for 12 hours and then switch the pump back on - the UV lamp will kill the bacteria created by the concentrate, but we believe that it multiplies sufficiently to remove the algae in sufficient numbers to survive the UV light for an extended period of time..So why 4 stars? Well this is an intermediate report, however, I think that whilst this product has contributed, so has the new pump, plus I get really irritated when suppliers contact me asking me to review their products too soon, not once, but twice, particularly as from their own instructions they suggest that you may not see results for weeks.+++UPDATE+++A month later and 5 doses of the product the water in the water feature is clear and the large cobble pebbles are losing the algae at a rapid rate. I intend to continue dosing the water feature through the winter, probably once a fortnight initially as the water feature is in a shaded area and will not have any direct sunlight at all until the spring, plus I believe that the low water temperature will not promote algae to grow either. If I am wrong I will increase the dose - suffice to say the water is now clear - a combination of pump and this bacterial agent.In essence, I believe that this product, combined with a better pump and filter; which I clean each week has aided our relatively small pond to rid itself of algae. I now have to buy netting as the clear water has already ensured that the heron has been spotted in our garden and whilst the water feature is very close to our house, I have no doubt that in the spring, the heron will pay a fleeting visit - in every silver lining lurks a cloud.I will re-review this item in a couple of weeks to see if my small water features water condition has improved still further - certainly the debris being removed from our filter suggests that it will and that this product is contributing.

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

This product cleared my wildlife pond in days, the water is now crystal clear. This uses beneficial bacteria to help clear the water rather than chemicals which helps keep the pond natural. I used one small cap full and the water is still clear over a month later.

Does the job it’s meant to, would buy it again

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.
