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.
