HYDRA ST-703 FEATURES & ADVANTAGES
Hydra ST703 quickly eradicates the most stubborn algae strains by starving them. The results should be visible within 3 to 7 days.
Algae infestations are common in the water with excessive nutrients, including nitrates and phosphates. Other conditions that support algae to thrive are abundant sunlight and warm weather. You would be able to clear filamentous algae of most types with popular algae treatment products available on the shelf. Still, some strains of algae are tough to get rid of. These stubborn algae forms do not respond to standard treatment products or procedures and retain their shape and colour even after the product application. Some of the most challenging algae strains to treat are Cladophoraglomerata, Enteromorpha Spirogyra, genus Charamacrophytic algae, Rhizoclonium, and some varieties of blanket weed.
Hydra ST703 is an outcome of the dedicated research efforts at ISO certified Hydra International Ltd. The product composition of Hydra ST703 includes a unique minerals and enzymes blend that rapidly starves off even the toughest algae. Hydra ST703 has an added advantage in its residual effect in the water, which means that the product actively keeps off algae long after the initial application. Unlike most other products, Hydra ST703 is effective even during cooler months of the year.

Will work at temperatures down to 6-8°C, although the action is slower at these temperatures. For the product to be most effective it is necessary that the water temperature is more than 10°C.
Having tried almost every blanket weed reducing product in the market I have had swift results from Hydra ST 703. I am quietly amazed that after just over a week there has been no further growth. I am more hopeful that this has worked than any other product I have ever used. Keep up the good work and thank you.

I've been using this product about once every 3 months since last year, and the algae is certainly very much more under control. So I recommend this product.

Cleared a fierce attack of algae growing from the bottom in 1 sprinkling over the surface.Left a couple of white stains on the bottom where heavy doses had sunk to. These don't seem to want to go.Water is extremely clear now.

I have tried different products from different companies over the years to reduce the blanket weed in my pond. A few years ago, I tried Hydra- Aqua Quartz, which I found very good at controlling the blanket weed, but last year I switched to ST703 and have been very happy with the product. I can see clearly down to the bottom of the pond and there is no blanket weed trying to grow on the side of the pond liner.

I haven't used this yet as there was a problem with delivery, but got it sorted with thanks to the customer service team. I'm delighted with the outcome and looking forward to blanket weed free pond.
