Hydra Fountain Clear Water Feature Cleaner | 250ml Treats 7,500L Highest Dilution Rates - Water Feature Treatment Keeps Water Crystal Clear from Algae, Cleans Water & Biofilm Build-up

I've bought this several times now and it works the best for me. Tried using a different brand that was cheaper and wish I hadn't bothered. This stuff keeps the water cleaner for longer and is not visible once added to the water. It is a little expensive but it's worth it if you want clean water. I will be buying it again.

I have used this product for a number of years. It is effective and easy to use with its built in measure so there is no mess and no waste.

I’ve used this to keep my small garden water feature and fountain water running clear. I don’t measure it out. I just pour a little in when I’ve had to top the water level up, and it’s been doing its job perfectly for most of this season. I suppose this could be thought of as being a little expensive but I’ve hardly used any and I’ve had no problems with green/dirty water or algae. My garden water feature is in full sun (when we’ve had some) for most of the day and I’ve been really impressed with this cleaner.

We were a little sceptical regarding this product, we were amazed , it’s fantastic , removed all the algae from the water feature and now it’s spot less . We only put approximately 1/4 of a teaspoon full in the feature. Would definitely recommend it

The clear water worked straight away as soon as it was in the fountain water colour was changed and the fountain ran normally

I’ve been looking for something that doesn’t harm birds or animals. This is perfect and keeps the algi away

put some in my fountain but it makes it a bit blue not sure if thats because I put too much i

Excellent product that keeps the fountain flowing freely,
