envii Water Feature Klear, Natural Water Feature Cleaner, Chemical Free Treatment Safe for all Wildlife & Pets – 20 Tablets Treats 2,000 Litres of Water

I bought these tablets because my water feature water was becoming cloudy. I choose this brand because it's natural and not harmful to animals.i put a tablet mixed with water into the wayer feature straight away and within a couple of hours the cloudy water was starting to clear , the following day it was totally clear , I would definitely recommend these tablets , it says repeat weekly but I'm hoping that because it's a small water feature it may last longer , we'll see !

Seems OK but hasn't taking the green of the stones yet.

I followed all the instructions but the buildup of algae never improved, even after cleaning with detergent the buildup was back. Much better products on the market just as pet or bird safe

Works well

Brand new water feature. Set the water feature up, followed the directions for adding the tablets and repeated a week later as instructed. In just two weeks my new water feature was full of algae and looked a right mess! What a complete waste of money! Out of desperation I added some white vinegar to the water in the water feature four days later the algae is gone and the water is clear. Forget all those expensive treatments, all you need to add to your water feature is some white vinegar. Job done, lesson learned! Don't try adding white vinegar to a fish pond though!!

Sorry it just doesn't work green keeps coming back

Our small fountain water feature has always suffered with algae. We have used bleach in the past, which has not been very successful. We have nine cats so we were very careful only to put in a small amount of bleach so this was probably partly why. Luckily the cats do not drink from the feature when the fountain is going so we kept it running all the time. We gave Envii a try this year after having given up for a few years and not using the feature at all. Without Envii the feature was green and slimy, and with feathery growth within two weeks. We cleaned it out thoroughly as per the instructions and used one dose of Envii. The algae did start to come back, but not as bad so we added a second dose as suggested and now the algae is disappearing. It appears to be being eaten! Well don Envii, we look forward to a clean feature for the rest of the year, and will certainly be buying again for future seasons.

Cleans water feature well
