Pool Water Dosage Assistant
Upload a photo of your test kit and enter the pH and chlorine values you see. The assistant will calculate recommended dosages based on a 100,000 L reference pool and scale for your actual volume.
On phones, for best results open this page in your main browser (Chrome on Android, Safari on iOS).
If any buttons don't respond, refresh the page or open it outside in-app browsers like WhatsApp or Facebook.
Dosage master ranges · 100,000 L reference pool
These tables summarise typical Blue Autumn dosage bands. The assistant scales values to your actual pool volume for each recommendation.
Free chlorine · Residential pools
Target: 1–3 ppm free chlorine for typical residential pools.
| Situation | Target (ppm) | Pool Chlorine 90% | Pool Chlorine 65% |
|---|---|---|---|
| Routine top-up (clear water) | +1 ppm | ≈ 110 g | ≈ 150 g |
| Low chlorine (0–0.5 ppm) | Raise to ≈3 ppm | ≈ 330 g | ≈ 450 g |
| Shock for cloudy/green water | 5–8 ppm | ≈ 550–900 g | ≈ 750–1,200 g |
pH adjustment & Megic Touch / Clarifier
Target pH 7.2–7.6. Actual requirement depends on alkalinity, bather load, and contamination.
| Measured pH | Adjustment | pH Minus | pH Plus |
|---|---|---|---|
| 7.2–7.6 | Within range | — | — |
| 7.6–7.8 | High | ≈ 400 ml | — |
| 7.8–8.0 | High | ≈ 700 ml | — |
| > 8.0 | Very high | ≈ 1.0 L | — |
| 7.0–7.2 | Low | — | ≈ 600 g |
| < 7.0 | Very low | — | ≈ 800–1,000 g |
pH doses assume 100,000 L and typical alkalinity. Adjust gently and retest rather than overdosing.
Algaecide & Megic Touch / Clarifier
These ranges are for reference only. Always brush thoroughly and maintain correct chlorine afterwards.
| Condition | Primary treatment | Helper product |
|---|---|---|
| Visible algae (green walls/floor) | Algaecide ≈ 600 ml | HTH Sparkle It ≈ 250 ml |
| No algae but cloudy water | — | Megic Touch ≈ 200 ml |
Use Megic Touch for ongoing algae suppression and water polishing in cloudy but non-green pools.
Use the clarifier mainly during green/very cloudy recovery.
