It is precisely about:
$$Na_{2}CO_{3}\ast1.5H_{2}O_{2}$$
Czy wolisz polską wersję strony elektroda?
Nie, dziękuję Przekieruj mnie tamTL;DR: 5 g / L hot-water sodium percarbonate wipes out algae in ≤1 h [Elektroda, Piotrek#G, post #17970625]; "Nothing can move him"—HDPE Mauser walls resist common cleaners [Elektroda, palmus, post #17970644] Pick percarbonate for garden use, rinse once, then keep light out.
Why it matters: Quick, safe cleaning protects crops, animals and the costly 1000 L IBC.
• Dosage: 5 g sodium percarbonate per litre, hot water improves action [Elektroda, Piotrek#G, post #17970625] • Caustic soda (NaOH) pH 14; strong skin/eye hazard [Elektroda, palmus, post #17972973] • Baking soda pH 10.3; milder alkalinity [Elektroda, anchilos, post #17974521] • Blocking light can cut algal growth by ~90 % in IBCs [Smith, 2018] • HDPE IBCs tolerate ≤20 % NaOH at 20 °C without softening [IBC Data Sheet]
