Hydroponics & Horticulture

In hydroponic and horticultural systems, plant success depends heavily on maintaining the right balance of nutrients and pH in the water or nutrient solution. The Milwaukee MW806 PRO is an essential tool for growers who want to take the guesswork out of this process.

Why Monitoring Matters:

pH Control: Each plant species has an optimal pH range – usually between 5.5 and 6.5 in hydroponics – where nutrient uptake is most efficient. If pH drifts outside this range, plants may experience nutrient lockout, where essential elements like nitrogen, phosphorus, or potassium become unavailable, even if they're present in the solution.

EC and TDS Monitoring: EC (electrical conductivity) and TDS (total dissolved solids) indicate the concentration of dissolved salts, which directly relates to nutrient levels. A reading that’s too high may result in nutrient burn, while one that's too low could signal nutrient deficiency.

Temperature Tracking: Solution temperature affects both nutrient uptake and dissolved oxygen levels. Keeping it within an ideal range (typically 18–22°C / 65–72°F) helps prevent root stress and supports healthy growth.

With the MW806, you can instantly check and adjust your nutrient solution to maintain ideal growing conditions – whether you're cultivating leafy greens, herbs, tomatoes, or ornamentals.

Agriculture

Water quality is one of the most critical – yet often overlooked – factors in agricultural productivity. Whether you're managing row crops, orchards, or greenhouse operations, the Milwaukee MW806 PRO helps ensure that your irrigation water and fertigation solutions are supporting, not hindering, plant health.

Why Monitoring Matters:

• Irrigation Water Quality: Poor-quality water with incorrect pH or high levels of dissolved salts (TDS/EC) can lead to soil salinity, poor nutrient absorption, or even crop toxicity. Monitoring these parameters helps prevent long-term damage to both plants and soil structure.
• Fertigation Management: Fertigation (the application of fertilizers through irrigation systems) requires careful control of nutrient concentration and pH to ensure nutrients are delivered in a form plants can absorb. If pH is outside the recommended range (typically 5.5 to 7.5, depending on the crop), nutrients like iron or phosphorus can become unavailable.
• Soil Solution Testing: By testing the leachate (water drained from soil), you can understand what nutrients remain available and whether salts are building up – a key insight for making irrigation and fertilizer adjustments.

The MW806 allows agricultural professionals to make informed decisions in real time, minimizing resource waste, optimizing yields, and protecting soil health for long-term sustainability.

How to Use the MW806 in Agriculture

1. Irrigation Water Testing

·        Collect a sample of water from your irrigation source (well, pond, or tank).

·        Turn on the MW806 and immerse the probe into the sample.

·        Wait for readings to stabilize, then note:

pH – Should be between 6.0–7.5 for most crops.

EC/TDS – Low values (0.1–0.7 mS/cm) are typically good; values above 1.5 mS/cm may require treatment or dilution.

Use these results to determine if your water needs pH adjustment or if high salt levels could stress your crops.

2. Fertigation Solution Testing

·        Before application, mix your nutrient solution according to guidelines.

·        Test with the MW806 to ensure:

pH is within the crop’s ideal uptake range.

EC/TDS is at the target nutrient concentration (varies by crop and stage).

·        Adjust as needed using pH up/down or by modifying fertilizer dosage.

Ensures you're delivering the right balance of nutrients without risking over-fertilization.

3. Soil Solution (Leachate) Testing

·        Collect runoff or leachate from soil after irrigation.

·        Test the solution using the MW806 to evaluate what’s actually reaching the root zone.

·        High EC values may indicate salt accumulation, while low nutrient levels suggest underfeeding.

Provides insight into nutrient availability and soil health.

Aquariums, Aquaculture & Aquaponics (Fish, KOI, Shrimp)

Maintaining water quality is essential for the health and well-being of aquatic life. Whether you're caring for ornamental fish in an aquarium, raising shrimp or koi in an aquaculture setup, or balancing the symbiotic needs of plants and fish in aquaponics, the Milwaukee MW806 PRO helps ensure that your water parameters remain in the safe zone.

Why Monitoring Matters:

pH Balance: Fish and aquatic organisms are sensitive to pH fluctuations. Most freshwater fish thrive in a range between 6.5 and 7.5, while saltwater species often require 8.0 to 8.4. Sudden pH shifts can lead to stress, disease, or even fatality.

Salinity Monitoring (EC/TDS): Conductivity and total dissolved solids (TDS) are indirect measurements of salinity and mineral content in the water. In aquaculture, maintaining the right EC/TDS levels ensures osmoregulatory balance, which is critical for fish health. In aquaponics, stable salinity also impacts plant root function and microbial health.

Temperature Awareness: Water temperature influences oxygen solubility, metabolism, feeding behavior, and immune response. Using the MW806, you can monitor temperature alongside pH and EC/TDS to keep all parameters in harmony.

In aquaponics systems, where fish waste feeds the plants and plants clean the water, imbalances can disrupt the whole ecosystem. The MW806 offers a comprehensive, handheld solution to check all key water quality indicators – quickly, easily, and accurately.

Whether you're managing a residential pool, public swimming facility, or a wellness spa, the MW806 offers the confidence of precise, on-the-spot testing.

Why Monitoring Matters:

pH Balance: Maintaining pH within the ideal range of 7.2 to 7.6 is crucial. If the pH is too low (acidic), it can irritate eyes and skin, corrode pool surfaces and equipment, and reduce the effectiveness of chlorine. If it’s too high (alkaline), the water can become cloudy, and chlorine becomes less effective, compromising sanitation.

TDS Monitoring: Total Dissolved Solids (measured through EC/TDS) represent the total concentration of dissolved substances such as minerals, salts, and organic matter. High TDS can:

·        Cause water to appear dull or cloudy

·        Reduce the efficiency of disinfectants

·        Lead to scaling on pool walls, plumbing, and heaters
Regular monitoring helps you decide when it's time to dilute the water or partially drain and refill the pool or spa.

Temperature: Though most pool users rely on a separate thermometer, the MW806 also provides quick temperature readings – helpful for balancing water chemistry (since chemical behavior changes with temperature) and ensuring comfort.

Whether you’re managing daily pool maintenance or troubleshooting water quality issues, the MW806 helps keep your pool crystal-clear and problem-free.

o   pH – Should be between 7.2–7.6.

o   TDS (ppm) – Ideally kept below 1500 ppm; values over 2000 ppm may require dilution.

o   Temperature – Useful for tracking comfort and chemical behavior.

Use the results to determine if you need to add chemicals (like pH increasers/decreasers or conditioners) or partially replace the water.

2. Post-Chemical Treatment Checks

·        After adding pH adjusters, algaecides, or sanitizers, wait at least 4–6 hours, then re-test.

·        Confirm that the water has returned to the target pH and TDS levels.

·        This prevents overcorrection or chemical imbalances.

Helps fine-tune your treatments and avoid unnecessary chemical use.

3. Weekly Deep Monitoring

·        Once a week (or more frequently for high-use pools), test TDS.

·        Compare readings to your usual baseline.

·        If TDS is consistently rising and passes 2000 ppm, consider a partial water replacement to maintain clarity and sanitizer efficiency.

Keeps your pool water safe, clean, and comfortable with fewer surprises.
