Longlife Algaecide


Price request




WTP C90 is a Long Life Algaecide with a copper active formulation.

Algaecides are an essential treatment in all pools. Algaecides prevent the growth and build up of algae.  The use of algaecides reduces the amounts of sanitiser consumed in preventing algae growth and thus enhancing the efficacy of chlorine treatment.


Physical State Clear blue solution with mild ammonical odour
pH 7.8-8.2
Specific Gravity (SG) 1.1  g ml-1 + 0.01


Algae growth in pools proceeds when a low free chlorine availability is present. The common cause being incorrect pH levels or high levels of chlorine stabiliser in the pool water. Green algae (chlorella) is the most prevalent strain in the UK.  Chlorine will kill most algae but if levels are low, or the water has out of balance problems the growth of algae escalates.  In a balanced pool with chlorine available, the algaecide supports the chlorine action by preventing growth of algae.  Algaecides reduce the amount of sanitiser required, enhancing the efficacy of chlorine treatment.  Small amounts of algaecide should be dosed throughout the season to prevent growth build up of algae and the subsequent problems.


A 30 ml dosage of product per 1000 litres of water gives an initial dose rate of 0.96 mg/litre copper (0.96ppm copper).

A top up dose of 12 mls/1000 litres of water gives 0.4 mg/litre copper (0.4 ppm copper).

Vacuum and backwash the filter. Shock dose using preferred chlorine/bromine sanitiser.  Add the required volume of WTP C90 for the size of pool by distributing evenly around the surface of the pool water. Leave the pump running for a further 24 hours.

Top up doses may be required at 3-6 month intervals subject to the use and condition of pool water.
