## Questions & Answers

**Q: What happens if to much is added**
A: A small amount is OK (5-10%), but if you add a lot more than the correct dose, there is a danger that the algae will die off very quickly and as the bacteria will degrade the dead algae much quicker than normal, they will reduce the amount of oxygen available for other pond life.

## Customer Reviews

### ⭐⭐⭐⭐⭐ A Great Product When All Else Failed
*by S***N on 25 July 2015*

Thank goodness this product seems to be doing the job of getting rid of Filamentous Algae. I've had a Garden Fish Pond for 30 years and never experienced algae like this before. Within a few weeks it spread all over the pond base at a thickness of around 150mm with huge lumps coming up to the surface during this years hot days. Using a pond vac helped but it seemed to grow just as fast. This Hydra ST703 came to the rescue and I can now report the pond is 95% clear. Will give a further dose later and currently using the pond vac on any sign of this algae.A Great Product and Many Thanks.
