My 29 gallon Oceanic Biocube is now 9 months old and it’s starting to see a healthy growth of coralline algae. Coralline algae is beautiful when it’s growing on the live rock, but not so much when it is growing on the glass and blocking the view into the tank. Fortunately it is very easy to clear and coralline algae is slow growing so you don’t have to repeat a cleaning like this very often.
If you have a glass fish tank then you can easily use a razor blade to clean off the algae from the glass but if you have an acrylic tank you need to be careful. An old credit card or anything with a nice plastic edge would work well on an acrylic fish tank. Make sure to start in an inconspicuous area of the tank first and go slowly to make sure you don’t scratch the acrylic. Here’s a video of me using an old XBOX Live card to clean my aquarium:
I would love to hear from you if you have a method for removing coralline algae that you would like to share. Please use the comment form below to share your methods and tips.
