Why is My Fish Filter Pink?

If you’ve noticed your fish filter is turning pink, there’s no need to worry. In most cases, it’s simply due to a buildup of algae on the filter media. While unsightly, this is not harmful to your fish or your filtration system and can be easily remedied.

There are a few things that can cause algae to grow on your filter media:

1. Excess light – Too much light shining on your tank can promote the growth of algae. If possible, move your tank to a location where it will receive less direct sunlight.

2. High nutrient levels – Nutrients like nitrates and phosphates can fuel the growth of algae. Be sure to perform regular water changes and vacuum the gravel to remove any excess nutrients from the tank. You may also want to consider using a phosphate remover in your filter if high levels are a persistent problem.

3. Temperature fluctuations – Sudden or extreme changes in temperature can cause algae blooms. Maintaining a consistent temperature in your tank will help prevent this from happening.

Serratia Marcescens Aquarium

Serratia marcescens is a species of bacteria that can be found in many different types of environments, including fresh and salt water aquariums. This organism is often mistaken for algae because of its reddish-brown coloration. However, S. marcescens is not an alga, but a bacterium that gets its red hue from the production of carotenoids.

This microbe can grow on a variety of surfaces, including glass, plastic, metal, and silicone. In addition to its ability to produce carotenoids, S. marcescens also produces several other pigments that give it a wide range of colors, including pink, yellow, orange, and white.This bacterium is often considered to be a nuisance in aquariums because it can cause cloudy water and discolored tanks.
