Why Test Low-Range Phosphate?
Phosphate testing is critical for preventing algae growth and maintaining water quality. In swimming pools, phosphates are nutrients that fuel algae blooms—even with proper chlorine levels, high phosphates (above 100-200 ppb or 0.1-0.2 mg/L) can cause persistent algae problems and cloudy water. In aquariums, excess phosphates promote nuisance algae growth that competes with plants and corals—optimal levels are typically below 0.05 mg/L for planted tanks and near zero for reef tanks. The MI512-25's low range (0-2.5 mg/L) is perfectly suited for these applications where phosphate levels should be minimal.
How to Use:
- Fill MW12 photometer cuvette with 10 mL water sample to line
- Tear open one MI512-25 powder reagent packet
- Pour entire contents into cuvette
- Cap and shake vigorously to dissolve powder completely
- Wait for color development (reaction time per instructions)
- Insert cuvette into MW12 Photometer and read phosphate concentration
Understanding Phosphate Levels:
Phosphate levels are typically measured in mg/L (ppm) or ppb (parts per billion). To convert: 1 mg/L = 1000 ppb. For pools, target phosphate levels below 100-200 ppb (0.1-0.2 mg/L) to prevent algae. For aquariums, target near-zero phosphates for reef tanks or below 0.5 mg/L for planted freshwater tanks. The MI512-25 low-range reagents provide the precision needed to monitor these critical low phosphate levels.
Storage & Handling:
Store reagent packets in a cool, dry place away from direct sunlight and moisture. Keep packets sealed until ready to use. Do not use damaged or expired packets. Follow all safety precautions on product labeling. Powder reagents offer superior stability compared to liquid reagents when stored properly.
Note: Milwaukee MW12 Low Range Phosphate Photometer sold separately. Reagents are consumable and must be replaced after use. For best results, use fresh reagents and follow all testing procedures carefully.
