Which Hydra Product to Use

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 the sample is green or cloudy, you either have excessive single cell algae or excessive suspended solids and need Hydra Crystal. If the water looks green in the pond or lake but is crystal clear or very slightly cloudy in the sameple, you have excessive nutrients and need Bio Aquatic Bacteria Boost.

Please refer to the table below to help you select products for other pond conditions.
