Algaecides?

Aquarium treatments can be purchased to resolve algae problems. Most of these treatments only kill the algae - they do not remove it from the water or prevent it from coming back.

How does the treatment work?

Once the treatment has been used the filter has to remove the dead algae from the aquarium. The filter is unlikely to be able to cope with all the extra work. If left in the aquarium the dead algae will decompose providing nutrients for more algae to thrive on.

Therefore, if you use an algaecide you must carry out lots of partial water changes to physically remove all of the dead algae. See below.

Also, you must tackle the cause of the problem. If you don’t the algae will simply return and you will have to start this hard work all over again.

Getting the water clear?

Use a Reef One cleaning pad to wipe algae away from the sides of the aquarium. The algae will then be trapped in the filter cartridge.

Keep an eye on the filter cartridge - as the sponge gets dirty remove it and wash it under the tap. By keeping it clear it will continue to trap the algae.

Carry out a series of partial water changes. Continue until the water is clear.

Do not replace all of the water in the aquarium as this will cause worse problems.
