  • Blue Green Algae (Cyanobacteria)

    Blue Green Algae (Cyanobacteria)

    Blue Green Algae is actually a bacterial slime and not a true algae. It quickly spreads, covering everything in its path with a thick green slime; occasionally taking on a black or dark purple coloring. Cyanobacteria is a nitrogen fixing agent, meaning that it will deplete all nitrogen forms (ammonia, nitrite and nitrate) from the aquarium.

    Common Causes
    • Unbalanced fertilization, especially focus on the nitrates and maintain 5-20 PPM levels.
    • Old light bulbs/tubes. As

  • Staghorn Algae

    Staghorn Algae

    An aptly named algae as it grows by branching. Depending on the lighting environment, algae can be green, grey or white. Firmly attaches to hardscape items, equipment and live plants Common Causes
    • Low or unstable CO2
    • Macros are in shortage or under fertilizing.
    • Tank maintenance insufficient
    • Uncycled tank, specifically having measurable ammonia




    Removing Staghorn
    • Increase CO2 levels to 30 PPM. Take some tank water and let it sit in a bucket for several days. Test the pH. Test your tank pH. 30 PPM

  • Grey Slime, Another Cyanobacteria

    Grey Slime, Another Cyanobacteria

    Another form of cyanobacteria. Grey-green to dark grey slime that moves upward as it grows. It can quickly cover plant leaves and suffocate the plant if not treated. This form of cyanobacteria readily pearls in a high light tank. When disturbed by fish or by attempts to remove is quickly dissipates into the water column, turning the water a light grey. Is often found with BGA, the other cyanobacteria.

    Common Causes
    • Chronic nitrate shortage
    • Old bulbs in light fixture
    • Overgrown plants
    • Lack

  • Euglena aka Green Water

    Euglena aka Green Water

    Euglena is a single celled organism that is a free floating form of algae. This algae form is an important organism in the global food chain. Some breeders will purposely grow green water to feed fry that need very tiny first foods for success. Green Water is impossible to cure if the root cause is not dealt with. There are many products sold that claim to kill the organisms that cause Green Water. However, it comes back very quickly and often stronger than before. These products simply fail because the root cause...

  • Green Spot Algae (Choleochaete orbicularis)

    Green Spot Algae (Choleochaete orbicularis)

    GSA is rarely noticed until it gets out of control as this is the point it grows into larger spots on plant leaves and begining to cover the glass. This is one form of algae that often goes after slow growing plants, such as anubias.

    Common Causes
    • Phosphates depleted. Be cautious when using test kits for phosphates. I have yet to use a kit that provided an accurate measurement! Calibrate a new test kit using KH2PO4 solution with a known phosphate level.
    • Insufficient Maintenance. Fresh water

  • Green Dust Algae

    Green Dust Algae

    It is easy to confuse GDA with Green Spot Algae (GSA). Instead of growing in spots like GSA does, Green Dust Algae is a green slime that will cover the glass and hardscape. What makes this a particularly difficult algae to remove is the fact that the slime, when disturbed, will release spores that will grow in other areas of the tank, thus spreading.
    Common Causes
    • Unknown, but seems to be more common in higher light tanks
    Removing Green Dust Algae
    • Wait for the algae to form thick patches and

  • Fuzzy Algae

    Fuzzy Algae

    Often goes unnoticed until it has gotten out of control. The form of algae grows in very fine threads that are difficult to see Common Causes

    • Low CO2. Try to maintain 30 PPM CO2 to stop this algae form.
    Removing Fuzzy Algae

    • Maintain a proper balance between lighting, fertilizers and CO2.

  • Diatoms or Brown Dust Algae

    Diatoms or Brown Dust Algae

    Diatoms will go unnoticed until they begin to cover everything. Once started this brown dust algae spreads very quickly and can choke out plants. The affected aquarium will turn into an ugly, monotone brown coloring. Thankfully, this algae is short lived.

    Common Causes
    • New Tank Syndrome. Not only do new aquariums need to be cycled, but they are subject to diatoms
    • Old Fluorescent Tubes. As fluorescent tubes age their output changes. This change in the color temperature of the light will lead to algae.

  • Cloudy Water

    Cloudy Water

    Every one of us who keep aquariums eventually notice that a tank is not as clear as it used to be. We have all asked ourselves "Why is my tank cloudy?"


    First step is to figure out what color the water is starting to take on. The best way to determine this is to look straight down into the tank.


    • Is the water green? This is an algae bloom. This

  • Cladophora

    Cladophora

    This string type algae is nothing short of your worst nightmare! It is often confused with hair algae, however, this form grows in thick mats that entangles itself into the plants and easily hides in other mosses. This is a difficult algae to remove as when disturbed it breaks into very tiny bits and pieces that go unnoticed. It is these tiny bits that attach to plants and start the cycle over again. ...
