How to Deal With Freshwater Aquarium Algae

A well-maintained aquarium is a very beautiful sight, but one thing that can spoil its appearance is algae.  It starts small, but once established in a freshwater aquarium algae can be very difficult to tame.  There are ways to control and deal with it and fortunately it rarely poses a health hazard to the fish, it just looks very bad.

The key to not developing an algae problem in the first place is properly locating the aquarium before it is even filled up.  When choosing a location a number of things must be considered: the floor strength, the room traffic, the vents/potential drafts, and the sunlight in the room.  The first few have nothing to do with algae growth, but are very important for the long-term health of the aquarium.  The last factor is the number one reason that people have algae problems in their aquarium.

It is very important that the tank be placed at a location in the room where it will not receive direct sunlight.  If the tank gets too much sunlight it may get too warm for one thing, but more importantly it will be very difficult to control algae growth in a tank that sits in the sun.  Almost every aquarium setup has some type of hood or cover and some type of artificial lighting on top, so the sun is not necessary to light up the tank.

The artificial lights in the hood of the aquarium can also be a potential source of algae overgrowth.  The issue here is whether or not live plants are present in the tank.  If they are then they will need the lights on to keep them healthy and growing, but it becomes a balancing act between providing for the plants and keeping algae growth down.

One thing that helps is to have some "algae-eater" fish in the tank such as plecos or Chinese algae eaters.  In reality, though, a whole school of them won't take care of an overgrown tank, but it doesn't hurt to have a few nibbling on the green stuff.  Plus, they are good looking fish that would be a good addition to most tanks anyway.

Scraping the algae growth on the sides of the aquarium is in most cases a necessary job, and if it is done on a regular basis the tank glass will stay clean and the algae situation will stay under control.  There are many types of scrapers and sponges to do the job including some magnetic ones that don't even require your hand to get wet.  Just be careful not to scrape too hard in the corners where the silicone caulking holds the sides together.

In the end, if freshwater aquarium algae continues to be a big problem for your tank, consider keeping the lights on for less time, scrape on a regular basis, and keep a few algae-eating fish.  If that doesn't work, then it may be time to relocate the tank within the room or house so that it gets less sunlight, and that will solve the problem.

How can i remove green algae from my tank?

Everytime i clean my aquarium the green algae grows back in a day or two, what can i do to stop this.

Rapid algae growth such as your case could be caused by multiple things.

1) High nutrients in the tank. There could be high levels of phosphates and other nutrients spurring the growth of the algae. Adding in plants like Coontail/Hornwart in freshwater or caulerpa in saltwater will help reduce the available nutrients in the tank. They will compete with the algae for the nutrients and eventually reduce the algae bloom. You can also use mechanical filters and pads to remove phosphates, etc, if you don't want the live plants.

2) Light. Sunlight spurs algae growth, so do old bulbs. Get the tank away from windows and areas where the sun hit it, even indirectly. Replace the bulbs on your tank if they are old (over a year). Unless you have coral or plants, you can reduce the hours you run your light to help control the algae as well.

3) Nitrate. This is similar to #1, and in addition, do more water changes to remove the nitrate and possibly treat with a nitrate reducing product, or use a nitrate sponge filter pad.

Now, that being said, you can also get critters to help you with your algae. Snails, algae eating fish, etc, are great helpers and will do most the "scrubbing" for you.

Your ID card or credit cards work great on safely scraping the algae off the sides of the tank.
