ASSESS THE POSSIBLE CAUSE - There are numerous reasons for algae blooms in a fish tank and the first step to getting rid of the problem is to find the source. Algae will grow abundantly in sunny and warm environments. If you have your tank near a window, try wrapping the tank with reflective background or moving the tank to another location. Over feeding your fish can also lead to an algae bloom, if you suspect this is the case, perform a water change and clean the gravel thoroughly (see article in resources for instructions). Only feed your fish as recommended by your local fish store or breeder.
USE YOUR ELBOW GREASE! Sometimes the only way to get rid of algae is with good old-fashioned elbow grease. You can purchase an algae scrub or sponge at your local pet store that will scrub off the algae but will not harm the tank surface. Take note of whether your tank is plastic or glass, you will need a different scrub-sponge for each. If you don't want to purchase a sponge, try using an old credit card to scrape the algae off the sides. Once you've removed the algae, change the water and clean gravel to remove the waste and scraped algae.
USE CHEMICALS ONLY AS A LAST RESORT - It is almost never recommended to chemically alter your fish tank's environment only because with patience it is a self-contained ecosystem. But if you have tried to remove the algae from your tank but have had NO success there are several chemical additives that will remove the algae for you. Always follow the label or the recommendation of your local fish expert.
PREVENT WITH NATURE - Fortunately for fish owners Mother Nature knew that algae would be a problem for us all at one point or another. Adding natural elements and creatures to your tank can be an excellent way to remove and prevent algae growth. Live plants compete with algae for resources and will usually win the battle. Plant a few in your tank to keep the chances of algae blooms to a minimum. There are several fish and snail types that will eat algae and keep it under control. The rubber-lipped plecostomus is perfect for 10-30 gallon tank sizes because they don't grow out of control like other plecos can. Another good choice for smaller tanks is the little algae-eater called the Otocinclus. He's great for little tanks with smaller fish as roommates.
