Users and applications
CTX-10 is chosen to lower the pH of pool water that has risen above 7.6. High pH reduces the effect of the disinfectant and leads to scale build-up. The granules bring the value back to within 7.2-7.6. The product is suitable for all pool types; the choice depends only on the measured pH and the pool volume.

// 03 · Installation and compatibility
Installation and compatible equipment
CTX-10 needs no installation; application is based on measurement. First pH is measured and the value is confirmed to be above 7.6. The dose is 150 g per 10 m³ of water and lowers pH by 0.2 units. After application, pH is measured again; if the target is not reached, the dose is recalculated according to the pool volume.
- The pH of the pool water is measured with a test strip.
- If the value is above 7.6, the reduction needed is determined.
- According to the pool volume, 150 g per 10 m³ is calculated.
- The granules are applied and pH is measured again.
// 04 · Maintenance
Maintenance checkpoints
CTX-10 is a consumable; renewal depends on the quantity remaining and the measured pH. The 1.5 kg pack suits small corrections and the 5 kg pack large volumes. The pack is kept closed. The granules are not mixed with chlorine products and are stored in their own pack. For reordering, the code is read from the label.
- The pack is closed after each use.
- The granules are stored separately from chlorine products.
- The quantity remaining is monitored according to the pool volume.
- For ordering, codes 03105 and 74650 are checked on the label.

+90 216 475 39 37Yes, CTX-10 is used to lower pH above 7.6. The granules increase disinfectant efficiency, improve bathing comfort and prevent scale formation. If pH is within 7.2-7.6 they are not applied; if below 7.2, CTX-20 is needed. Before use, pH is measured with a test strip; the dose is calculated from the result and the measurement is repeated after application.

150 g of granules is added per 10 m³ of water, and this quantity lowers pH by 0.2 units. In larger pools the quantity increases in proportion to the volume, and in a smaller pool it decreases. After each application pH is measured again; if the target is not reached, the dose for the remaining reduction is recalculated and the application is repeated.
Çilek Havuz Corporate
The choice depends on the pool volume and how much the pH is to be lowered. The code for the 1.5 kg pack is 03105 and for the 5 kg pack 74650. The standard pack quantity is 20 for 1.5 kg and 4 for 5 kg. The 5 kg pack is used for large volumes, the 1.5 kg pack for small corrections.

CTX-10 lowers high pH, CTX-20 raises low pH. CTX-10 is used when pH is above 7.6, CTX-20 when pH is below 7.2. CTX-10 prevents scale formation, CTX-20 metal corrosion. The two are not used at the same time; the pH measurement determines the choice. The pack options also differ: CTX-10 1.5 and 5 kg, CTX-20 1 and 5 kg.
Çilek Havuz Corporate
Yes. Water whose pH stays above 7.6 leads to scale build-up; CTX-10 prevents this by bringing pH to within 7.2-7.6. It also increases disinfectant efficiency. For the effect to last, pH is measured after application and at regular intervals; if the value rises again, the dose is repeated.

They are not added at the same time; pH is adjusted first, then chlorine is applied. The CTX care routine begins with the balance step, followed by the disinfection step. Chemicals are stored in their own packs and are not mixed. CTX-300 Slow-Dissolving Pool Chlorine Tablets are used for continuous chlorine, and CTX-200 Pool Shock Chlorine Granules for fast chlorine.
Çilek Havuz Corporate
pH is measured with Pool Water Test Strips & Kits. The 7-parameter and 3-parameter test strips read pH. Measurement is made before and after applying CTX-10. This shows whether the value has fallen below 7.6 and whether the granules are needed again, so unnecessary dosing is avoided.
