Getting to the bottom of Fish Tank Issues

There's a lot that can affect the water quality in your aquarium – and solving these issues can be tricky. But don't worry, it happens to even the most seasoned fish owners.

In this helpful guide, we'll explore the three most common issues that fishkeepers face and provide effective solutions to ensure your aquarium thrives!

Cloudy Water Issue: 
Causes and Solutions

Cloudiness in aquarium water can stem from overfeeding, overstocking, or New Tank Syndrome.


  • Appropriate Filtration: Ensure your filter is adequately rated for the size of your aquarium.
  • Regular Filter Maintenance: Change the filter cartridge every month to maintain optimal performance.
  • Impeller Cleaning: Clean the filter, especially the impeller, every other month to prevent clogs.
  • Water Quality Testing: Use Tetra® Test 6 in 1 to test water quality regularly and perform a 25% water change monthly.
  • Feeding Adjustment: Reduce the frequency and amount of fish feeding, by closely monitoring their food consumption.

What is an impeller?

An impeller is a driven rotor used to increase the pressure and flow of a fluid. It is the opposite of a turbine, which extracts energy from and reduces the pressure of a flowing fluid.

What is New Tank syndrome? New tank syndrome’ is commonly experienced in the first weeks of a new aquarium and is caused by an immature filter and excess waste.

Green Water Woes: 
Understanding Algae Overgrowth

Green water is often caused by excess algae, triggered by factors like direct sunlight, overfeeding, or high phosphates.


  • Water Change and Cleaning: Conduct a 50% water change and clean the interior glass of the tank.
  • Artificial Plant Maintenance: Clean artificial plants and ornaments with a vinegar solution.
  • Feeding Habits: Adjust feeding habits to once or twice a day in small doses.
  • Phosphate Management: Address high phosphate levels with a new water supply or Tetra® Algumin™.

Bad Smelling Water: 
Dealing with Fishy Odours

Foul odours indicate excess waste, primarily from overfeeding.


  • Water Quality Check: Test water for high ammonia and nitrite levels, changing 50% of the water if needed.
  • Feeding Control: Cut back on feeding to reduce excess waste production.
  • Proper Filtration: Ensure your aquarium has an adequately sized filter.
  • Stocking Guidelines: Avoid overstocking by following the guideline of 25.4 mm of mature fish per 3.8 litres of water.

Remember - regular monitoring, thoughtful feeding practices, and diligent maintenance are the keys to a successful and enjoyable fishkeeping experience.
