Fixing Your Freshwater Algae Problem in Your Fish Tank

Shannon Frye
It's difficult to get rid of an algae problem. When you want to remove the algae problem, you need to remove the source of all of the problems. You will need to first purchase a timer for your freshwater fish tank. If you have your light on for more than 6 hours every day, you have an algae problem because you are heating the tank up too much. The excess light is forming the algae that you see on your fish tank. You can purchase these timers from any local pet store or hardware store. You plug them into the outlet and plug the light into the timer. Then you can set the light to come on and off at certain times.

Now you will want to unplug and remove your filter system. You will need to throw away the old filter cartridges. Remember that you must change these every time you clean the tank, once every two weeks. Now you will need to grab an old toothbrush and scrub every single part of your filter system. You will want to clean the inside of all of the tubes and the outside and inside of the intake tube. Clean the entire filter until there's no gunk or grime on the filter system on the inside. Grab new filter cartridges, and rinse them in cold water. Now you can place them in the filter system and set it aside.

Now you will need to clean your fish tank. You will need a scraper to remove the algae from the inside of your fish tank. You can purchase scrapers which look like a razor blade but they are made from plastic. This will do a good job removing all of the algae from your fish tank. Clean the inside of the tank, heater and bubbler as well. Remove all visible algae from the inside of your fish tank.

Now you will want to siphon the gravel to remove the algae from the rock. Use your siphon tube and go over all over the rock very well. This will remove all of the algae from the rock. The next time that you clean the rock you will need to switch sides every time that you clean the rock. You are only cleaning all of the rock this time to remove all of the algae from your fish tank. If you keep up on water changes at least once every 2 weeks, you will no longer have an algae problem after today.

    Argh! This is a nightmare. How do your fish survive? Seriously? You are giving some great advice on some of your articles, but at the same time you are giving the poorest advice I've ever seen! If you throw your filter cartridges away every two weeks, you won't get a beneficial bacterial build up on your sponge, which is what you want, regardless of whether your filter has a bio compartment or not.
