PROBLEM
POSSIBLE CAUSE
SOLUTION
Cloudy Tank
This can typically occur during initial set up as a result of the biological balance trying to
establish itself in the aquarium or as a result of overfeeding.
Perform a partial water change (up to 25% of the water). Add in a dose of Fluval Water Conditioner and a dose
of Fluval Biological Enhancer. Reduce your feedings to once every two days until you see positive results. If this
does not work, test your water by bringing a sample of the aquarium water, as well as a sample of the tap water
to your local pet store.
Lethargic fish
This often results during initial set up or at other times when the water quality is poor.
When there are high levels of ammonia and nitrites, the fish tend to instinctively stay
closer to the bottom and conserve their energy by moving less. It is hard for them to
breathe in poor water conditions.
Perform a partial water change (up to 25% of the water). Add in a dose of Fluval Water Conditioner and a dose
of Fluval Biological Enhancer. Reduce your feedings to once every two days until you see positive results. If this
does not work, test your water by bringing a sample of the aquarium water, as well as a sample of the tap water
to your local pet store.
Spotted fish (Ich)
If you notice white spots on your fish, along with uncharacteristic behavior, this may be
a sign that your fish is sick.
Consult with your pet store and they can recommend an appropriate remedy.
Smelly water
When there are high levels of ammonia, nitrites and nitrates, in addition to cloudy
water, a foul smell can result.
Perform a partial water change (up to 25% of the water). Add in a dose of Fluval Water Conditioner and a dose
of Fluval Biological Enhancer. Reduce your feedings to once every two days until you see positive results. If this
does not work, test your water by bringing a sample of the aquarium water, as well as a sample of the tap water
to your local pet store.
Green Water
Green water is caused by the growth of algae. Algae is a plant that requires light and
nutrients to grow. In order to prevent its growth, shield your tank from the light and
make sure you are feeding a high quality fish food. Perform a 25% water change every
4 days. Cut back on feeding, use a high quality fish food, dose with Fluval Biological
Enhancer, as well as the Fluval Water Conditioner with every water change. If the
situation does not remedy itself within 3 weeks, it is possible that the green water is
occurring for another reason.
If you are not sure why you are having a problem with your aquarium, bring a sample of the aquarium water, as
well as a sample of the tap water to your pet store so that they can test it to determine the cause and guide you
to an appropriate course of action.

Note: Most water quality problems are caused by introducing too many inhabitants at one time or over feeding. Add inhabitants 1-2 at a time and feed only what
can be consumed within 2 minutes.
