Water chemistry and nutrient dynamics form the foundation of a healthy pond ecosystem, directly influencing fish health, aquatic vegetation, algae growth, and overall water quality. The FRESHWATER Chemistry Panel with Comprehensive Nutrient Bundle combines essential water chemistry measurements with a complete nutrient profile to provide an in-depth assessment of pond or lake conditions.

This test includes:

• pH: Measure of acidity or alkalinity affecting biological processes
• Hardness: Calcium and magnesium concentrations important for fish health and herbicide efficacy
• Alkalinity: Buffering capacity that stabilizes pH and supports productivity
• Total Salinity: Overall concentration of dissolved salts in the water
• Total Ammonia Nitrogen (TAN): Combined ammonia forms indicating potential toxicity
• Un-ionized Ammonia: Toxic fraction of ammonia that can harm fish
• Nitrite: Intermediate nitrogen compound that can be toxic to aquatic organisms
• Chlorides: Important for osmoregulation and reducing nitrite toxicity
• Total Phosphorus (TP): All forms of phosphorus present in the water
• Soluble Reactive Phosphorus (SRP): Immediately available dissolved phosphorus that can fuel plant and algae growth
• Organic Phosphorus: Phosphorus stored within algae, bacteria, and organic matter
• Total Nitrogen (TN): Total nitrogen present in the system and a critical driver of biological productivity

This bundled panel provides a comprehensive understanding of water quality and nutrient conditions:

• Determine whether water chemistry supports healthy fish populations
• Identify potential toxicity risks and limiting factors
• Compare water chemistry results with acceptable and optimal ranges
• Distinguish between immediately available and biologically stored phosphorus
• Evaluate the overall nutrient load driving aquatic plant and algae growth
• Identify potential imbalances between nitrogen and phosphorus
• Receive science-based recommendations for corrective actions and future management

This test is ideal for pond and lake owners seeking the most complete assessment of their water. Results can support decisions related to fish stocking and health, fertilization, aquatic vegetation, harmful algal blooms, water clarity, and long-term water quality management.

Sample Requirement: 16–20 ounces of water

Note: If your water sample is “muddy” or contains a large amount of suspended silt and clay, an additional $15 filtering charge will be invoiced before analysis. This charge offsets the additional labor and materials required to prepare the sample. If you already know that your sample will require filtering, you may add the charge to your order .

Results take a minimum of 7 days from the date the sample is received.
