Do you have cloudy aquarium water in your display aquarium? Here are the most common types of cloudy aquarium water: White cloudy water is usually indicative of a bacterial bloom.
Green cloudy water is usually an algae bloom
and yellow cloudy aquarium water is usually a result of high levels of dissolved organics or using new drift wood.
Read on to find out how to deal with each of these water quality issues.
If your tank has been set up for a short time this may be the result of a bacterial bloom that happens in a newly set up tank or when too many fish were added too soon. This cloudy aquarium water will correct itself when a sufficient amount of bacteria establishes on your biological filter. See the Nitrogen Cycle for more information on this process.
You can help keep your tropical fish from getting stressed by performing 25% water changes daily and feeding them less until the nitrogen cycle has finished.
To correct this problem, perform 25 percent water changes daily, rinse out or replace the filter media to reduce the amount of nitrates, feed your fish a little less and leave your tank light off for a few days or until the water clears up. If you do practice good aquarium maintenance and still have algae problems, look into testing your tap water. You may be introducing nitrates and possibly phosphates into your tank via the water changes and not even know it. Also look into keeping live aquarium plants which will compete with the algae for available nutrients.
Pond keepers sometimes use a UV Sterilizer on their outdoor ponds to help control algae growths. While we agree that these sterilizers can have a positive effect on the algae growth in your tank, there are better, less expensive methods to use for controlling algae in the aquarium and we recommend you try some of the ideas presented above.
If that doesn't work, as a last resort, you could use Aquarium Pharmaceuticals Algae Destroyer. The algae destroyer should clear up the algae problem quickly. Please use as directed on the bottle. This is just a quick fix and we recommend that you figure out what's causing the algae problem in the first place.
To best way to fix the yellow coloration of your tank water is to perform more frequent partial water changes along with the use of activated carbon. Activated carbon has many uses in an aquarium filter including removing small amounts of DOC, removing water smells and making the water look cleaner or polished. Try to change out the carbon on a regular basis, at least every 3 to 4 weeks if not sooner.
