====================================================================================
     THE UNIVERSAL CISTERN CHLORINATION FORMULA (METRIC & US GALLONS)
====================================================================================

 [RULE 1] ONLY USE PLAIN, UNSCENTED LIQUID SODIUM HYPOCHLORITE BLEACH
   * Check the label for exact percentage: Standard household bleach in the US/Canada
     is now typically 7.5% to 8.25% Sodium Hypochlorite (older or economy brands are
     5.25% to 6.0%; pool liquid chlorine is 10.0% to 12.5%).
   * NEVER use "Splash-Less," "Easy Pour Gel," "Lemon/Lavender Scented," or "Color-Safe"
     bleach (contains toxic soaps and hydrogen peroxide).

 [RULE 2] THE EXACT METRIC MATH (Using Standard 6% Household Bleach):
   * For 1 ppm Free Chlorine per 1,000 Liters: Add 17 mL of 6% bleach.
   * For 5 ppm (Routine Tank Re-Sanitizing): Add 85 mL of 6% bleach per 1,000 L.
   * For 20 ppm (Heavy Bio-Contamination Shock): Add 340 mL of 6% bleach per 1,000 L.
   * For 50 ppm (Emergency Carcass / Pipe Shock): Add 850 mL of 6% bleach per 1,000 L.

 [RULE 3] CHECK THE pH BEFORE ADDING BLEACH (Optimal pH = 6.5 to 7.2):
   * Rainwater is naturally slightly acidic (pH 5.5 to 6.5), which is GREAT for
     chlorine efficacy (forming 90%+ lethal Hypochlorous Acid, HOCl). However, in
     NEW CONCRETE or FERROCEMENT cisterns, lime leaches out and raises water pH to
     8.5 - 9.5, where chlorine loses 80% of its germ-killing power.

The 6-step procedure for shocking the cistern and indoor plumbing lines¶

1. Step 1 (Siphon Out the Bottom 3 Centimeters of Anaerobic Sludge First):
2. Look at the floor of your rainwater tank: even a clean roof deposits a 1- to 3-centimeter (1/2- to 1-inch) layer of decomposed pollen, leaf dust, and bird droppings at the bottom of the tank. If you dump bleach into a tank without vacuuming out that bottom organic layer first, 90 percent of your chlorine reacts with the bottom mud within 30 minutes, leaving zero free chlorine to kill pathogens and generating foul-tasting chlorophenols.
3. Connect a 25-millimeter (1-inch) weighted siphon hose (or portable utility transfer pump) attached to a long PVC pole and vacuum the bottom floor sediment out onto non-edible bushes.
4. Step 2 (Pre-Dilute and Circulate the Chlorine Dose):
5. Pour the calculated volume of unscented bleach into 20-liter (5-gallon) ngaahi pakete vai pea lilingi ia takatakai 'i he perimeter 'o e cistern ('oua 'aupito na'a ke lingi 'a e raw undiluted pool granules ki ha fungavaka PVC/liner manifinifi, 'a ia 'oku nau fakahinehina mo embrittle 'a e pelesitiki).
6. Ke fefiofi 'a e chlorine tatau 'o fakafou 'i ha tangike lita 'e 10,000, fakafehokotaki ha hose ngoue ma'a ki ho'o pamu 'o e 'omi 'o e spigot 'i tu'a, tuku hifo 'a e nozzle ki mui ki he 'olunga 'o e cistern hatch, pea recirculate 'a e tangike ki he ** 30 ki he 45 miniti ** lolotonga hono fufulu hifo 'a e loto citern 'o e dome 'i 'olunga andwhere rodent urine and spider webs sit).
7. Sitepu 3 (To'o 'a e Vai Chlorinated Ki he Paipa Vela mo e Momoko Kotoa pe 'i Loto):
8. Bypass pe to'o ho'o loto Ngaahi kato 'o e filita kaponi 'oku faka'aonga'i mo e Reverse Osmosis (RO) Memipa (50 ppm chlorine destroys RO membranes and exhausts carbon blocks immediately), 'o tuku 'a e ngaahi fale pelesitiki filter 'ata'ataa screwed 'i he feitu'u ko ia 'oku ma'u 'e he ngaahi fale 'iate kinautolu pe 'a e sanitized.

10. Sitepu 4 (Puke ki he 12 to 24 Hours mo e Sivi Toenga Kololini Tau'ataina):
11. Tuku ke tangutu 'a e vai kuo kololini 'i he vaitupu mo e ngaahi paipa 'i he houa 'e 12 ki he 24.

Fakauku ha Strip Sivi 'o e Kololini Ma'olunga (DPD Free Chlorine strip) ki he vaitupu hili ha houa ʻe 12: kuo pau ke ke kei maʻu ha siʻisiʻi taha ʻo e 100. 2 to 5 ppm 'o e Kololini Tau'ataina 'oku toe hili 'a e houa 'e 12.
