WATER QUALITY MONITORING & TESTING

Maintaining excellent water quality is one of the most important factors in successful aquaculture operations. From commercial fish farms and hatcheries to research facilities and advanced Recirculating Aquaculture Systems (RAS), accurate water monitoring and testing provides the information needed to maintain healthy stock, improve growth rates, and optimise system performance.

At Pure Aquatics, we provide professional water quality monitoring solutions designed for modern aquaculture environments. Our range of testing equipment, monitoring systems, filtration solutions, UV sterilisation, ozone treatment, and oxygen management technologies help aquaculture operators maintain stable and productive aquatic systems.

HEATHLY STOCK

Improve survival and growth

STABLE ENVIRONMENT

Maintain optimal water conditions

BETTER PERFORMANCE

Lower costs and higher productivity

EARLY ALERTS

Detect issues before they become problems

KEY WATER QUALITY PARAMETERS

Understanding and monitoring key water quality parameters helps you maintain a stable environment and ensure the health and performance of your aquatic stock.

Dissolved Oxygen (DO)

Essential for respiration, feeding, growth and overall fish health.

Why it matters:

  • Low DO causes stress
  • Reduces feed intake
  • Can lead to mortality

PH & ALKALINITY

pH affects fish health, ammonia toxicity and biological filtration.

Why it matters:
Rapid changes cause stress
Influences nutrient availability
Affects biofilter performance
Products to insert:

View pH Testing Solutions ›

Produced from fish waste and uneaten feed. Highly toxic even at low levels.

Why it matters:
Damages gills
Reduces growth
Increases disease risk
Products to insert:

View Ammonia Test solutions ›

Produced during the breakdown of ammonia. Interferes with oxygen transport in fish.

Why it matters:
Causes “brown blood disease”
Reduces growth
Increases stress

TEMPERATURE

Affects metabolism, oxygen demand, feeding activity and disease risk.

Why it matters:
Higher temperatures reduce oxygen
Influences growth rates
Affects system stability

SALINITY & CONDUCTIVITY

Important for marine and brackish species and osmoregulation.

Why it matters:
Affects animal health
Impacts reproduction
Essential for consistent conditions
Products to insert:

View Salinity Meters ›

The final stage of nitrification. Less toxic but indicates waste buildup.

Why it matters:
Indicates biofilter performance
High levels require water changes
Products to insert:

View Nitrate Testing ›

TURBIDITY & WATER CLARITY

Measures suspended particles in the water.

Why it matters:
High turbidity affects gills and growth
Reduces light penetration
Indicates poor filtration

THE ROLE OF FILTRATION & WATER TREATMENT

Water testing identifies problems – filtration and treatment help solve them.

Removes suspended solids, uneaten feed and organic waste.

Benefits:

  • Cleaner water
  • Reduced biological load
  • Improved clarity


View Filtration Systems ›

Supports beneficial bacteria that convert toxic ammonia into less harmful compounds.

Benefits:

  • Essential for RAS
  • Supports nitrification
  • Improves water quality


View Biofiltration Media

Helps reduce pathogens, bacteria and some parasites in the water.

Benefits:

  • Improves water quality
  • Ideal for hatcheries
  • Enhances system safety


View UV Sterilisers ›

Powerful oxidation that breaks down organics and improves water clarity and quality.

Benefits:

  • Reduces colour & odour
  • Improves oxygen transfer
  • Enhances RAS performance


View Ozone Generators

Increases dissolved oxygen levels and improves circulation.

Benefits:

  • Supports fish health
  • Promotes waste removal
  • Essential for high density systems
