How Should You Deal With Excess Algae in Your Aquarium
Aquariums will always have a small amount of algae present and this is fine, it can be a source of food for your fish. It only becomes a problem when it is present in excess when it makes your tank look ugly and coats your decorations and artificial plants. It is usually caused by having the lights on for too long periods. Although it looks ugly it won’t harm your fish and it is easily corrected by the methods outlined below.
How Should You Remove or Reduce the Growth of Algae?
Reducing excessive growth can be accomplished by:
- removing the algae by hand
- using fish or organisms that eat algae
- reduce the length of time you keep on the tank lights
- do partial water changes every two weeks
How Should You Remove Algae by Hand?
You can use algae magnets or brushes to remove the algae but this needs to be done carefully. The excess algae must be removed from the tank not simply dislodged as it will only settle again and continue to grow. Rinse the magnet or scrubber under the tap frequently.
Should You Reduce the Lighting Times to Deal with Algae?
Tank lights should be left on for a maximum of twelve hours, preferably less until the algae problem is cleared up. Use an automatic timer if you tend to forget!
Use Fish and Other Organisms to Eat the Algae
Some fish are great at eating the algae such as yellow tangs, angle fish and blennies. Snails and hermit crabs will also feast on it and help to keep it under control.
How Often Should You Change the Water?
Partial water changes of up to 30% should be done at least every two weeks. Never completely change the water as you will remove the good bacteria! Change the filter pads frequently and avoid using any chemicals or treatments in the tank. It’s a good idea to have a quarantine tank ready to treat any sick fish. Adding chemicals to the main tank can be a cause of many aquarium problems!
