HYDRAFountain Clear Water Feature Cleaning, 2x250ml Treats 15,000L Highest Dilution Rates, Fountain Cleaner Treatment Keeps Water Crystal Clear from Algae, Green Water, Biofilm Build-up

The bottle is very small but when you read the instructions on how much to put in you understand. The product is very good put it in our water feature which the birds like to bath and the water is very clear. Well worth buying

Works well,used for a long time. Excellent at removing and keeping algae at bay.

Good product, it does keep water clear.

Not a large bottle! However, works well and requires very little to keep water and fountain clear. Good stuff!!

Works realy well , gives off a nice clear water stream . Very pleased with the product

Really easy to apply

I use this in my garden fountain and it keeps algae in check. I find I need to use slight higher dose than advertised but that's not a problem.I would recommend this product for keeping water feature water clear and sparkling.

After a month or so, it does seem to be doing its job well. I always have some concerns with these chemicals as I have had those that don't keep the water very clean. The matter of wildlife safe is a concern too and all you can do is hope the manufacturers are telling the truth. At least I haven't had any birds fall from the sky after bathing or drinking from our water feature.The dilution rate of this is unbelievable and I was a bit concerned oh how I was going to measure out 1ml for each weekly treatment. Or course that's just under 1/4 teaspoon which is easy enough, but you really don't want to get this stuff on your skin/clothing/anything at all! I had one drop on the uPVC doorstep and it left a yellowing mark in no time at all before I could rinse it off. Now I use a very small 1ml syringe I managed to obtain instead.As it does seem to work and the amount in the bottle will last more than a year, the value for money is great. I highly recommend giving this a try.
