Beginner-Friendly Cloudy Water Fact Sheet: Cloudy Aquariums
Cloudy water is a common issue in aquariums, but it’s easy to fix with the right knowledge! Here’s a simple breakdown of what causes it and how to solve it.
What Causes Cloudy Water?
Bacterial Bloom: Too much food or waste in the water feeds bacteria, making the water look milky.
Infusoria: Tiny creatures that eat the bacteria can also cloud the water.
New Tank Syndrome: New aquariums often go through a cloudy phase as they establish beneficial bacteria.
Overfeeding: Uneaten food breaks down and feeds bacteria.
Poor Filtration: Insufficient filter media or over-cleaning can disrupt beneficial bacteria.
How to Fix Cloudy Water
Don’t Panic! Cloudy water is usually harmless and will clear on its own.
Stop Overfeeding: Feed only what your fish can eat in 2-3 minutes, once or twice a day.
Upgrade Your Filter: Replace cartridges with foam blocks or pot scrubbers for better bacteria growth.
Avoid Over-Cleaning: Only clean filter media when water flow slows down.
Add Aeration: Use an air stone or increase surface agitation to support beneficial bacteria.
Be Patient: New tanks can take weeks to clear as bacteria colonies establish.
