Weekly, Biweekly, and monthly maintenance is an important part of keeping a healthy aquarium.

Water changes are essential to a successful aquarium.

A water change should be performed approximately every 2 weeks. Usually 10-15% is enough.

It is essential to check the new water you introducing to the aquarium. Tap-water can contain chlorine or chloramine which must be eliminated before putting in the tank.

Local tap water can also contain phosphates, iron and other heavy metals. Call your local water company to find out about your tap-water chemistry.

Testing

It is essential to check water chemistry on a regular basis.

The vital parameters to test in your aquarium are pH, nitrates, nitrites, and carbonate hardness and salinity for marine tanks.

pH should be at 6.5 – 7.5 for most species.

Nitrites should be zero at all times (except during cycling). If nitrites are detected make sure you check your ammonia also.

Nitrates should be kept below 10 ppm in freshwater and 5 ppm in marine and reef (preferably 0 ppm).

Recommended Maintenance Routine

Daily

• Be aware of how your fish are acting, changes in behavior can indicate a potential problem.
• Check your equipment to ensure it is running properly.

Weekly

• Keep an current inventory of the livestock in your aquarium. Dead animals can decompose very quickly, which can easily cause an ammonia and/or nitrite spike, which then lead to high nitrate levels.

Every Other Week

• Test your water : pH, ammonia, nitrite and nitrate (salinity in salt and reef tanks).
• Vacuum the gravel and change 10-20% of the water.
• Clean the aquarium glass.
• Rinse filter cartridges with the the water you pulled from the tank.
• Replace carbon and filter floss (if present).
• Inspect all equipment and parts for proper operation.
• Wipe clean your aquarium top glass so that your lighting is not affected.
