BiotekFountain Clear - 500ml - All Natural Fountain Cleaner Treats Up To 12500 Liters

Clears any slime and algae

Seems to be working well. Essential to clean out the water feature thoroughly before use. Important to put in the bottom level of a multi-levelled water feature to avoid excessive foaming or scum line appearing. Used 3 times so far and water remaining clear.

Having purchased two water features last year (both solar powered fountains) I hadn't realised that after a few weeks, especially in the summer heat, the water and the bowl of the fountains would become badly discoloured. Because of the different materials that the fountains were made of one turned green and the other pink. This meant that I now had to empty and clean the fountain and water.on a regular basis. As birds drink from one of them I couldn't use any chemicals. I'm delighted with the results of using this product. The water stays clear, the birds are safe and the fountains look fab!

Ok, but i wouldnt say it works that well if you accidentally put to much in the water goes cloudy

So far so good

Used for Bird Bath, must say I am delighted at this product. No more scrubbing out the bird bath, water stays clear for quite a while before I have to change the water. The only negative I would say is that the measuring side of bottle needs tob easier to use as I couldn't get the solution to travel into its compartment. Could use though as I used other side judging how much solution to release.

I used this in my three tier water feature. For the first few weeks it did not seem to have any effect, but gradually the water did start to clear, and it has been clear now for quite a while. However, the green staining around the bowls had to be cleaned manually. Better still, as it is a natural product, the birds are able to drink the water with no ill effect.

Appears to working well so far and at a good price compared to other retailers too
