What could be the cause of red aquarium water?

The water in my aquarium is turning red.


Answer by  h (364)

The cause of red aquarium water is normally because you added some type of tablet for the plants. Generally, these tablets contain some amount of iron. The iron in the tablets can cause the water in the aquarium to turn red. If this is the case, the plant tablet may also harm the fish. Check the label to make sure.

Dirty water. You need to do a water change asap and a good cleaning. Waste due to overfeeding and fish waste will build up in the tank, which will make the water look pink/red. Make sure you clean the gravel and plants well and keep to a water change and cleaning schedule to prevent this.

Red water in a fish tank is usally caused by red algae taking hold and multiplying in the aquarium. This is very hard to get rid of. One fish you can put in your tank that is very good at controling it by eating it is the Siamese Algae Eater.

This is caused by algae, and the tank needs to be disinfected. You need to drain the water, remove the fish, and thrown out all the plants and gravel.
