Pool parameters

mg/L
TCCA tablet dose33.3 g
Pool volume60.0 m³（60,000 L）
Chlorine boost needed0.50 mg/L
Calcium hypochlorite (65%)46.2 g
Sodium hypochlorite (10%)300 g（≈0.30 L）

How it works

  1. 1Volume = 10 × 5 × 1.2 = 60.00 m³
  2. 2Target 0.8 mg/L (GB 0.3-1.0), boost = 0.8 − 0.3 = 0.50 mg/L
  3. 3Pure Cl = volume × boost = 30.00 g (1 g per m³ per mg/L)
  4. 4TCCA (90% avail.) = 30.00 ÷ 0.9 = 33.3 g

GB 37488-2019: free chlorine 0.3-1.0 mg/L, pH 7.0-7.8, water 23-30 °C; foot-bath pool 5-10 mg/L, changed every 4 hours.

Per CJJ122-2017, chlorine products must be pre-dissolved and dosed wet into the circulation line — never throw granules directly into the pool.

A strong "chlorine smell" is chloramine (from sweat/urine), meaning under-chlorination, not cleanliness. Test free chlorine every 2 hours during operation.

Chlorine demand rises with bather load and sun (UV); tablets dissolve slowly — recheck and top up rather than mega-dosing.
