Instructions
Clean your filter regularly. Loud buzzing noises signal that carbon and grit are caught in the filter's impeller well. Hold the filter upside down and back flush it with water. You can also physically take out the impeller should rinsing not work.
Assess the tank's flow control valve. If water comes into the tank faster than the valve can accommodate, noise can result. Place the overflow elbow at horizontal, then adjust the valve to allow in less water. Do this adjustment in increments, spacing them out by two minutes each.
Check the drain pipe if your filter makes a slurping noise. Water flowing too quickly to the wet/dry filter can cause this. Install a ball valve between the filter and drain to remedy this. The valve causes pressure to raise the level of water in the overflow box, which stops the loud sound.
Keep the powerhead filter away from the tank's glass. Consider placing it in a large sump to muffle its noise.
Replace worn parts in a filter. Old shafts and bushings in particular can cause aggravating noises.
Opt for a more powerful, higher-quality water filter. Such a filter will be reputed for its ability to reduce the volume of water flow in the tank, further reducing noise. These filters also change the tank water twice an hour, instead of four to five times an hour (like lesser-quality filters).
How to Eliminate Aquarium Filter Noises
Filtration, sterilization and water movement are an aquarium filter's primary functions. Quiet is also crucial; it characterizes a piece of equipment that runs properly. Filter noise can result from manifold circumstances in a tank. You should consider the type of filter to troubleshoot the exact source of the noise. Proper filter maintenance can pre-empt sound issues, as can monitoring the level of water flow. When in doubt, fully replace the filter with a newer model.
