7 ml per m³ raises free chlorine by 1 ppm in fresh stock; expect to dose more as drums age.

Do I need a metering pump?

Strongly recommended for daily use. Manual dosing is fine for emergency shocks but not routine.

Can I store it long term?

No. Strength decays 10-20% over 90 days at 20 C and faster in summer; rotate stock.

5 L, 10 L and 25 L HDPE bottles. Bulk 200 L or 1000 L on request for plant rooms.

Is it the same as bleach?

Same active ingredient as household bleach but at twice the strength and pool-grade purity, no fragrances.

14% w/w sodium hypochlorite, equivalent to roughly 14% available chlorine when fresh.

What is the active ingredient?

Sodium hypochlorite (NaOCl) at 14% w/w available chlorine.

Why does it raise pH?

Sodium hypochlorite hydrolyses to release hydroxide ion alongside the active chlorine.

No. Sodium hypochlorite is unstabilised; no cyanuric acid is added.

Stock has decayed; rotate drums and recalibrate pump.

Pair with a pH Minus dosing schedule or auto pump.

Liquid is cheaper per ppm and easier to auto-dose; cal-hypo stores for years and needs no pump. Liquid for daily plant rooms, cal-hypo for emergency stock.

Liquid vs TCCA tablets?

Liquid hits free chlorine instantly and adds no CYA; tablets are slow and stabilised. Liquid for plant rooms, tablets for unattended garden pools.
