Copper Sulfate Pentahydrate In Swimming Pools

Therefore it should not be used as part of your regular pool chemical treatment.

Copper sulfate pentahydrate in swimming pools.

One part per million of copper in drinking water is quite safe and 0 5 parts per million is enough to control green algae in swimming pools. This reaction is known as hexaaquacopper. Most copper sulphate contains around 20 25 copper so a 50 000 liter pool would require 100 120 grams copper sulphate if the pool is green i would give a once off double dose. This frees up low levels of chlorine or salt chlorine to be more active and available.

The american journal of public health recommends using copper sulfate in swimming pools only as a method to control growth of algae. This is simply 6 water molecules h2o bonded to a copper cu2 cation. Poolrx minerals dissolve out of the unit in the first 24 hours and form a stable residual throughout the entire body of water killing algae and bacteria. Copper sulfate otherwise known as bluestone is sometimes used in swimming pools as an algaecide.

Copper sulfate does not replace the need for pool sanitizers such as chlorine. Copper sulfate pentahydrate cuso4 5h2o is added to water it dissolves quickly giving us the crystal clear bluing of hexaaquacopper ii ions cuh2o 6 2 above. Copper sulfate does not eliminate the need for chlorine bromine or other pool sanitizers. Copper sulfate is also used in order to help with public health and safety.

Copper based algaecides and algaestats are the commonest source of copper salts for pools but copper sulphate is also a preventative treatment and an effective cure for many algae attacks. Copper salts react with chlorine to produce cupric oxide and and may cause grey black stains on pool surfaces.
