  1. ALGAECIDES. There are some chemicals that have been developed primarily to control and kill algae. Since there are many different such compounds, it is best when using them, to be guided by the manufacturer’s instructions. Generally chlorine must be used in conjunction with algaecides.
  2. CHLORINE STABILIZER (CONDITIONER). The use of this substance assists in the stabilization of chlorine to permit longer periods of protection. If stable chlorine is used as a regular source of chlorine the conditioner need be added only once with each filling of the pool. If other types of chlorine are used, the stabilizer should be replenished about every 3 to 4 weeks. See directions on stabilizer container regarding the amount to use.
  3. HOW MUCH CHLORINE IS REQUIRED? It is advisable to follow the directions of the manufacturer for his particular products. As a rule this will provide dosages that will produce satisfactory results for normal treatment. During the initial start up, it is advisable to double the dosages shown for the first few days.

Due to stabilization action, test pool for chlorine before adding. If chlorine is   present in water reduce dosage proportionately.

For effective control of bacteria and algae maintain a chlorine residual of 0.3 to 0.6 ppm.
