Hydra International - Natural Aquatic Treatments, Cleaning & Protecting the Environment

Aquatic Problem Solver

Remember ALWAYS take a water sample Before deciding what your water problem is, it is absolutely essential that you take a sample of water from your pond or lake into a clear glass and hold it up to the light - if you just look at the body of water you will never get the true picture.

If it’s green or cloudy you either have excessive single cell algae or excessive suspended solids and need the following Hydra Aqua product:

• Pond with exterior filtration system (not filter on submersible pump) - Hydra Crystal
• Pond without an exterior filter system - Hydra Pond Clear Plus
• Lakes which normally do not have any filter system - Hydra Rapide
• Fountains - Hydra Fountain Clear

If the water looks green in the pond /lake but is crystal clear or very slightly cloudy in the glass you have excessive nutrients and need:

• Spring - Summer: Bio Aquatic Bacteria Boost
• Autumn - Winter: Hydra LT Extreme

Please check chart below for your own particular problem.
