Lo-Chlor is Australia's most trusted specialist pool and spa chemical manufacturer globally recognised and exporting to 25+ countries. Their range covers algaecides, clarifiers, phosphate removers, stain treatments, stabilisers, spa care, equipment aids and more, every product formulated for Australian water chemistry and climate.
The Lo-Chlor Starver Test Kit is the dedicated phosphate testing kit for Lo-Chlor's Starver phosphate remover range — providing fast, accurate phosphate level readings using liquid reagents for professional-grade results.
Testing before and after phosphate removal treatment is essential. Without testing, you can't know whether your phosphate levels are causing your algae problems, whether you're dosing the right amount, or whether treatment has actually worked. The Starver Test Kit removes all guesswork — giving you an accurate reading in under 2 minutes.
Lo-Chlor Starver Test Kit details
Accurate liquid reagent phosphate testing — more reliable than test strips
Suitable for pools and spas
Fast results — under 2 minutes per test
Professional-grade accuracy for home use
Specifically designed for use with the Lo-Chlor Starver phosphate remover range
Essential tool before and after any phosphate treatment
Use the Starver Test Kit before choosing your phosphate remover: under 300 ppb suits Starver M for monthly maintenance; 300–1,000 ppb suits the original Starver; above 600 ppb or very high levels warrant Starver X for fastest results.
🔍 Which pool types?▾
The Starver Test Kit works with any pool type.
🧂Salt chlorinated▾
✓ Compatible — essential for salt pool phosphate monitoring
Salt pools accumulate phosphates from sunscreen and body products. Monthly testing helps stay ahead of phosphate spikes before they fuel algae growth.
💧Traditional chlorine▾
✓ Compatible — all pool types
Works with any pool chemistry. Simply collect a water sample and follow the test instructions.
🪨Mineral / magnesium▾
✓ Compatible
Works with mineral pool water without interference.
⚡Ionised / Nature2▾
✓ Compatible — particularly important for ionised pools
Phosphate testing is especially important for ionised pools — algae can establish quickly in these systems if phosphate levels rise.
🏊Fibreglass▾
✓ Compatible
Works with water from any pool surface type.
🧱Concrete / pebblecrete▾
✓ Compatible — critical for black spot prevention
Regular phosphate monitoring is the most reliable way to prevent black spot algae from returning in pebblecrete pools after treatment.
🧪 How to use▾
Simple 3-step test process. Follow the included instructions for accurate results.
Step 1
Collect sample
Fill the test vial to the marked level with pool water. Collect from mid-pool depth, away from inlets and returns.
Step 2
Add reagents
Add the liquid reagents as directed and mix. The water will change colour within 1–2 minutes.
Step 3
Read & act
Compare colour to the chart. Under 300 ppb = maintenance dose; 300–600 ppb = standard treatment; 600+ ppb = Starver X.
Test frequency
Every 4–6 weeks
Test monthly during peak season. Test before and after any phosphate treatment to confirm results.
❓ FAQ▾
Do I need to test if my pool looks clear?▾
Yes — phosphates are colourless and odourless. A pool can have very high phosphate levels with no visible signs, until algae suddenly establishes quickly when conditions are right. Knowing your levels proactively is far easier than treating a problem after it starts.
What level should I be aiming for?▾
Below 200 ppb is ideal. Under 300 ppb is acceptable for most pools with regular algaecide dosing. Above 300 ppb, phosphate removal is recommended. Above 600 ppb, use Starver X for fastest knockdown.
Can I use standard DPD test strips for phosphates?▾
Standard DPD test kits measure chlorine, pH and alkalinity — not phosphates. Phosphate testing requires a separate dedicated kit like the Starver Test Kit. Some multi-parameter test strips include phosphate, but liquid reagent tests are significantly more accurate.
