If are thinking about adding an algae eater, you will need to provide it space to live and grow too. You will also need to keep the water around 77F/25C, which is too warm for for goldfish ideally prefer. For these reasons, don’t add an algae eater. It’s not necessary anyways.
- To clean the water take out 50-75% of the goldfish bowl’s water and replace it with clean water that contains no chlorine. You can add a few drops from a dechlorinator to remove any chlorine from the water.
- If you are careful and act quickly to do the water change, you can probably leave the goldfish in the goldfish bowl you are cleaning.
- During this time you can scrub off any algae with a clean rag with no chemicals or detergents in it. We recommend an algae scrubber that you can get from your local pet store.
Note that a little bit of algae in a tank is a good thing. It adds oxygen into the water and provides a good source of snack food for your goldfish.
