Hydra Fountain 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

A goodbl product . It works well and keeps the water clear

This really is a brilliant product. My little water feature used to be green with algae within a few days, and I was constantly scrubbing it clean. I started using this 4 weeks ago and not a trace of green. Just 2 drops once a week is enough to keep the water algae free, so it's very cost effective.

Tiny bottle, easy to use & it has kept my water fountain water lovely and clear

Excellent product clears fountain and lasts a long time. Only need small amount for fountain. Is expensive but worth money as I have bought cheaper products and they have not worked

I have a small birdbath with a solar fountain. Despite having 6 pre 1982 copper coins in it, I was still having to scrub it out once a week and unclog the solar fountain. Since using this product there has been no more green. I only use 6 DROPS as it is super concentrated. I have not had to clean the birdbath for nearly a month now. I just top it up with tap water and I haven't even added more drops in this time. Safe for animals and birds but does kill flies wasps and bees (unfortunately for the bees if they try to drink it).

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.

This product did clear the water to a degree in my small water feature, however I was disappointed it did not remove the black slime that collects on the ball head of the fountain, as is claimed that it would. Personally I will be trying a different product in the future.

Seems to work well
