+90 216 475 39 37Yes, CTX-300 is used for continuous disinfection. The product dissolves slowly and contains stabilised chlorine; the chlorine mixes into the water over time and the effect lasts a long time. It is suitable for a general maintenance routine. The product is sold in 1, 5 and 25 kg packs. The chlorine value is still measured regularly with a test strip.
Çilek Havuz Corporate
Yes. Alongside continuous treatment, CTX-300 is also suitable for shock treatment. If chlorine needs to be raised very quickly, the fast-dissolving CTX-200 Pool Shock Chlorine Granules are more suitable. Both are stabilised chlorine; the dissolution rate differs. When used for shock treatment, the dose is calculated separately according to the pool volume and chlorine is monitored by measurement.
Çilek Havuz Corporate
They are used in all pool types. The product has no pool type restriction; there is no need to choose a separate product for liner, polyester and other pools. CTX-200, by contrast, is suitable only for liner and polyester pools. If the pool type is not known, CTX-300 can be chosen; the choice is still guided by the chlorine requirement.
Çilek Havuz Corporate
The choice depends on the pool volume and chlorine consumption. The code for the 1 kg pack is 03154, for the 5 kg pack 03156 and for the 25 kg pack 19195. The standard pack quantity is 20 for 1 kg, 4 for 5 kg and 1 for 25 kg. The contents of all three are the same.
Çilek Havuz Corporate
Slow-dissolving means that the chlorine mixes into the water over time rather than all at once. This is why CTX-300 is chosen for continuous disinfection. For shock treatment, where a fast effect is wanted, the fast-dissolving CTX-200 is used. Both products carry the same type of chlorine, namely stabilised chlorine. The chlorine value is still monitored by measurement.
Çilek Havuz Corporate
10 g is added per 10 m³ of water. This is much lower than the CTX-200 dose of 150 g per 10 m³; the two products are not added in the same quantity. In larger pools the quantity increases in proportion to the volume. Chlorine is measured again after application; if the value is low or high, the dose is reviewed.
Çilek Havuz Corporate
Yes, they are used together. Disinfectant efficiency improves when pH is balanced, so pH is measured first. If pH is above 7.6, CTX-10 is applied; if it is below 7.2, CTX-20. Continuous chlorine is then maintained with CTX-300. The two products are stored in their own packs and are not mixed. Measurements are taken with Pool Water Test Strips & Kits.
