Hydra Fountain Clear Water Feature Cleaner | 60ml Treats 1,800L Highest Dilution Rates - Water Feature Treatment Keeps Water Crystal Clear from Algae, Cleans Water & Biofilm Build-up

It works well and keeps water clear. Remember to remove all or most of the water first and clean the old alge prior to using product. This product is not a magical potion that will erase built up green gunk, you'll need to do your bit and clean the old alge first.

Works very well. Water now crystal clear

A very small bottle but goes a long, long way. It may seem expensive but you only need a ml to start off with

Does a good job

It’s a very small bottle - but a little goes a long way - it works too !

Very quick delivery, but small bottle unable to get syringe into neck of bottle to measure quantity to add to water.

Works great

Very tiny bottle I knew it would be small only 60ml but seems a lot smaller than I thought. Seems to work at keeping the water clean.
