INDEPENDENT WATER INTELLIGENCEActivated Carbon: Taste Breakthrough or Residual Loss
Carbon adsorption can improve taste but also remove disinfectant residual and eventually lose capacity.

Marine Water Knowledge Base
A technical reference on water treatment, disinfection, materials, biofilm, corrosion and the control of vessel drinking-water systems.
TECHNICAL REFERENCE
Find guidance by topic
Browse marine treatment technology, water chemistry, biofilm, corrosion and operational controls. Every guide explains how the process works, its benefits, limitations and what to monitor on board.
Log water checks digitally
Record drinking water and pool/spa measurements, follow trends and open reports securely.
Crew Water Monitoring →TROUBLESHOOTING & DIAGNOSTICS
Open troubleshooting guides →Find the cause before treating the symptom
Practical onboard fault guides for water colour, odour, biofilm, pressure, filters, corrosion and pool/spa. Check, record and escalate instead of guessing.

Biofilm or Slime Returns After Cleaning
Recurring slime may indicate persistent water age, nutrients or poorly treated internal surfaces.
Preview article →Blue or Green Water at a Tap
Blue/green staining or coloured water can point to copper corrosion, but backflow or other contamination must also be excluded.
Preview article →Brown, Black or Orange Water
Discoloured water may contain iron/manganese deposits, corrosion products or disturbed tank sediment.
Preview article →Earthy, Musty or Stale Water
Persistent musty smells may be associated with source-water compounds, aged water, carbon filter condition or microbial growth.
Preview article →Filters Block Too Quickly
Frequent cartridge changes are a symptom; the source of solids and hydraulic conditions must be identified.
Preview article →Fuel, Solvent or Chemical Taste/Odour
A fuel-like or solvent-like odour is a potential contamination event requiring immediate escalation.
Preview article →Galvanic Corrosion at Mixed-Metal Connections
Dissimilar metals electrically connected in a conductive electrolyte may accelerate attack on the less noble material.
Preview article →Low Pressure or Uneven Flow at Outlets
Low pressure can be mechanical, hydraulic or caused by fouling, and should not be misdiagnosed as low-water quality.
Preview article →Metallic Taste or Coloured Staining
Metallic taste can reflect pipe materials, stagnation or changing water chemistry; taste does not identify a specific metal.
Preview article →Milky or Cloudy Water
White cloudiness can be entrained air, calcium-carbonate particles or other suspended matter.
Preview article →Pinhole Leaks or Pitting in Stainless Steel
Stainless steel can pit or suffer crevice corrosion in chloride-containing, stagnant or poorly designed environments.
Preview article →Pool/Spa: Cloudy Water or Unstable Disinfectant
A cloudy spa or pool can reflect filtration, bather loading, water chemistry or insufficient disinfection.
Preview article →Rapid Metal Damage: Stray Current or Galvanic?
Unexpected rapid metal loss can involve electrical leakage but not every corrosion defect is stray-current corrosion.
Preview article →Repeated Microbiological Positives
Recurring positive laboratory findings call for investigation of the whole source-to-outlet system.
Preview article →Rising Watermaker Permeate TDS
Increased RO product conductivity can signal changing source conditions or membrane/system problems.
Preview article →Rotten-Egg or Sulfur-like Odour
A sulfide-like smell may arise from the source, a heater, microbial activity or a local drain.
Preview article →Unexpectedly Low Free-Chlorine Residual
A low measured disinfectant residual can reflect consumption, a faulty reading or treatment removal.
Preview article →UV-C Alarm or Low Reactor Intensity
A glowing lamp is not proof of adequate UV dose; alarms require verified response.
Preview article →White Scale in Hot-Water Equipment
White deposits and declining heating efficiency can indicate calcium-carbonate scale formation.
