Full instructions on the label.

Hydra Fountain Clear is special multi-action anti microbial formula, which is effective against a large species of algae, air borne bacteria, and various slime or bio-film producing microbes. The product significantly lowers corrosion of the water systems by reducing harmful and unappealing slime deposits. Circulating water is effectively sterilised and pathogen growth minimized by product application in all types of water circulating systems.



Use Hydra Fountain Clear to sterilize water in all water re-circulation systems and water features. The product helps you get clear water fountains. Special non-foaming, no-ionic, odourless formula acts effectively even at diluted rates and poses no harmful effect on the environment.  Hydra Fountain Clear does not remain in the water for long and quickly decomposes into environment- friendly by-products.

The product is not suited for water with pH levels above 9.0 because of rapid hydrolysis.

Customer Reviews

Crystal clear
Having suffered awful green water in my small garden fountain I turned in desperation to Hydra Fountain clear. After a thorough cleaning and wash through of pump and pipes, problem solved. Some weeks later after hot, sunny and humid conditions just adding a small "shot" each week has kept my water clean & clear. Highly recommended. Review by Barry
clear in a day
Only used on a small kelkay waterfall, so minimal amount needed for the amount of water. Cleared it with no issues now crystal clear.

Review by Savion
Keeps water clear
I've used several products over the years but this is one of the most effective and sensibly priced ways to keep our water feature clear. Definitely worth trying.
Review by Andrew
Clear Water Algae Killer
This product made a dramatic difference to my solar fountain. After initial dose I have added just a few drops each weeks and the water is crystal clear. I was previously emptying the fountain every couple of weeks and scrubbing it to clear the algae. Highly recommended.
