Water parameters

Aquarium Water Parameters Tracker for Every Fish Tank

Log fish tank water parameters, review test history, and spot trends before small changes become bigger problems. Aquarium Tracker keeps pH, KH, GH, ammonia, nitrite, nitrate, phosphate, and other readings organized by tank.

What Are Aquarium Water Parameters?

Aquarium water parameters describe the chemical conditions inside a fish tank, such as acidity, hardness, nitrogen-cycle readings, and nutrient levels. They change over time due to feeding, filtration, plant growth, water changes, and biological activity.

See your data clearly, then act on it

Aquarium Tracker turns every water test into a clear story. Log multiple parameters at once, filter by date, and review past measurements to understand what is really happening in each tank.

Log each test session

Add several parameters at once so strips, liquid-kit results, and meter readings become a complete aquarium test results log.

Aquarium parameter charts with trend lines

Learn from trends

Filter by date, look back across months, and spot patterns in nitrate, phosphate, CO2, hardness, and pH on clean charts.

Parameter table with recommended ranges highlighted

Make every number useful

Set recommended ranges with horizontal lines on charts, sort parameters in your preferred order, and review everything in a full data table.

Parameters You Can Track

Track the aquarium water parameters that matter most for your fish tank, planted aquarium, shrimp tank, or reef setup, including detailed NO3 and PO4 readings.

Temperature

Tracks daily stability and helps you match conditions to livestock needs.

pH

Measures acidity or alkalinity and influences how comfortable fish and plants feel in the tank.

KH

Carbonate hardness helps stabilize pH and buffers sudden swings.

GH

General hardness reflects minerals like calcium and magnesium needed for healthy livestock.

Ammonia (NH₃/NH₄)

Signals early biofilter performance and should stay near zero in mature tanks.

Nitrite (NO₂)

Tracks the nitrogen cycle and should remain near zero in a stable aquarium.

Nitrate (NO₃)

Tracks waste buildup and fertilizer levels so you can balance plant growth and fish health.

Phosphate (PO₄)

Helps you keep nutrients in balance and avoid sudden algae swings.

TDS

Useful for shrimp and specialized setups where total dissolved solids matter.

Conductivity

Shows overall ion concentration changes, especially in planted or softwater tanks.

ORP

Reflects water oxidation-reduction potential, often used in reef and high-tech systems.

Salinity

Essential for brackish and marine tanks to keep livestock stable.

Iron (Fe)

Tracks micronutrient dosing for healthy plant coloration and growth.

Potassium (K)

Supports plant health and balances macronutrient dosing.

Magnesium (Mg)

Supports plant growth and influences overall water hardness.

Calcium (Ca)

Important for invertebrates, coral growth, and overall hardness balance.

Copper (Cu)

Track trace levels when using medications or tap water with copper content.

Zinc (Zn)

Optional trace element tracking for planted or reef tanks.

Manganese (Mn)

Monitors micronutrients tied to plant health and dosing routines.

Boron (B)

Supports plant growth and can be monitored with trace dosing plans.

Molybdenum (Mo)

Optional micronutrient tracking for advanced planted setups.

Why Tracking Water Parameters Matters

Consistent logs help you spot trends early, adjust routines before problems grow, and keep nutrient levels in balance. Over time, an aquarium test results log supports healthier livestock, steadier plant growth, and clearer decisions.

If you track nitrate and phosphate changes, a clear timeline makes it easier to see how nutrients respond to feeding, dosing, and water changes.

How Aquarium Tracker Helps

Aquarium Tracker lets you log aquarium test results in seconds, review history and trends, and compare numbers against your own ranges without complicated setup. You can track multiple aquariums side by side, making it easier to stay consistent.
