Ebb and Grow: Growing and Controlling Algae in Your Aquarium
Controlling nutrients is our best means of preventing, repressing and essentially controlling algae in the aquarium
I have two large aquariums in a school setting. Our biggest problem is controlling algae. I have tried liquids, pills, etc. but it comes back. In one of the tanks I have put snails in hopes of help. Is there a product that I can use safely in the aquarium with the snails.?
Controlling the length of time the aquarium receives light -- called the photoperiod -- can also help control algae. An electronic timer for your lights can make it easier to control the photoperiod. Set your lights for 6 to 8 hours per day. With a shorter photoperiod, any algae that need intense lighting will shrink back. If the problem persists, you can up the photo period to 8 to 12 hours per day. Some algae thrive under low-light conditions, so upping the lighting can discourage their growth. Sometimes experimenting is the best way to find the right amount of lighting for your specific tank.

Let's face it: sooner or later, the day comes for every aquarium owner when they look in their tank and discover those green tufts or coating, growing on the plants or glass. Algae strikes again, and perhaps this time it's your tank that's the victim?
Don't panic. Algae can be a nuisance, but it can also be controlled. Notice I did not say eradicated; I said controlled. Despite its bad reputation, algae is just as much a part of nature as any other plant. It is a rare tank that is, and remains, completely algae free. However, it is reasonable to expect to hold algae down to a minimum.Like any plant, for algae to grow it has three basic requirements: water, light and nutrients (ammonia and phosphate). So the best method to controlling and preventing algae in your aquarium is by controlling the amount of light and nutrients in your water.Here's an strange sounding tip for reducing the time you spend cleaning algae from the glass: dose sodium silicate to promote a controlled population of diatoms. Diatoms! I know... bear with me.
Most aquarist's introduction to diatoms is as an unsightly reddish-brown coating of their sand and rocks in the first few weeks of a new aquarium. At that point, most decide that diatoms are a "Bad Thing (tm)" and are forevermore willing to do anything at all to avoid diatoms or even the possibility of diatoms. When diatoms are out of balance (like that bloom in a new aquarium), they don't do anyone much good. But when diatom populations are in a stable balance with other processes in your tank, they are very good for the whole system.
Good things for aquarists might include: Although controlling and preventing algae is the common goal of most fish owners, having a little bit of algae can help add character and authenticity to your aquarium. You might even have had the thought of as it does give your Guppies some nutrition value.
