Green Water

One particular of the greatest difficulties facing pond owners is green water. This takes place when minute forms of water daily life this kind of as algae get out of control and start off taking over the pond. These can contain mixtures of the two totally free floating and suspended species such as blanket weed, silkweed and mermaids hair. Algae can quickly choke up garden ponds and generate an unattractive ‘pea soup’ physical appearance.

Is green water caused by an unhealthy pond?

Numerous individuals believe green water is a signal of an unhealthy pond. However green water can have an effect on all types of ponds and is common in people that are wealthy in nutrients. Even nicely balanced ponds can suffer from green water and this is common in spring. At the starting of the expanding season a temporary film of algae can bloom on ponds as the water commences to warm up.  This is not a lead to for concern as typically when the other aquatic plants start to develop the algae bloom will disappear once again.

Typical Difficulty Species

There are some far more persistent varieties of water existence even though that will need to have to be handled. Blanket weed in certain can kind a very thick mat-like development across ponds which can be challenging to remove. This can block light from the pond triggering submerged plants to die. Silkweed can also be a troublesome addition to ponds and will tangle close to water lilies and submerged plants ruining the visual look of ponds.  Silkweed can be removed by hand but it is extremely slippery and this can be a aggravating and time consuming job.

Biological Therapies

Biological treatment options can provide some good results when treating green water. With biological remedies pond owners aim to generate a natural balance that will discourage algae from spreading prolifically.  This includes two major strategies:

Submerged Plants – by producing a enough level of submerged aquatic plants pond owners can guarantee that spare plant meals obtainable in the water are used up. This will discourage algae from forming as there will be few spare nutrients for it to feed from.

Surface Shade – all-natural surface shade from water lilies and other floating foliage can decrease the light falling beneath the water and discourage algae from developing.

Marine Daily life – specific species of marine lifestyle this kind of as ramshorn snails and fresh water muscles can act as normal algae filters.  They can’t clear a green water pond alone but will support to maintain a natural balance.
Chemical Treatment options

For significant green water difficulties often chemical substances are the only answer.  Algicides can clear green water quickly and can aid to avert it from returning just before a much more normal balance of plants can be attained.  There are two primary varieties of algicide:

Potassium Permanganate – products with this chemical base are used for suspended algae issues and green water. This can only be used when the water is amazing otherwise it can harm marine lifestyle and flip the water a yellowish colour.

Copper Sulphate – goods with this chemical base are powerful against each filamentous and suspended algae but only extremely minute concentrations are protected to use if you have marine lifestyle this kind of as fish and molluscs.
