Rainbar for Dolphin C-500 canister filter
The rainbar for the Dolphin C-500 is designed to improve water circulation and create gentle, even surface movement in your aquarium. When connected to the canister filter’s outlet, the rainbar spreads the return flow across multiple small holes, producing a soft, uniform current that benefits fish, plants and overall water quality.
This type of flow distribution helps reduce strong jets, prevents stress in sensitive fish and increases surface agitation, which supports better oxygen exchange. It’s especially useful in planted tanks, community tanks and aquariums where calmer water movement is preferred.
Made from durable, aquarium-safe materials, the rainbar fits securely onto the Dolphin C-500 outlet system and is simple to install or adjust. You can position it horizontally or slightly angled to achieve the circulation pattern that works best for your setup.
Replacing a damaged or missing rainbar helps restore efficient water movement and ensures that your filtration system performs as intended.
Suitable for both freshwater and marine aquariums, the C-500 rainbar is a reliable accessory for maintaining healthier and more balanced tank conditions.

The intake pipe for the Dolphin C-500 is an important replacement part that ensures your canister filter can draw water from the aquarium efficiently and consistently. This pipe guides water from the tank into the filter, where it passes through the mechanical, biological and chemical stages before returning clean and oxygenated.
A cracked, clogged or weakened intake pipe can reduce suction, affect flow rate or place strain on the filter. Replacing it with a correct-fit C-500 intake pipe restores optimal water movement and helps maintain stable filtration performance.
Made from strong, aquarium-safe materials, this intake pipe is designed specifically to fit the Dolphin C-500 model. It attaches securely, is resistant to wear and is simple to install during regular maintenance or when upgrading worn components.
Suitable for freshwater and marine aquariums, the intake pipe supports healthy tank conditions by ensuring the filter receives a steady and reliable water supply.
Outlet pipe for Dolphin C-500 canister filter
The outlet pipe for the Dolphin C-500 is a replacement part designed to restore smooth and consistent water return to your aquarium. This pipe directs filtered water back into the tank, helping maintain strong circulation, proper oxygen exchange and an even flow pattern throughout the aquarium.
A damaged, cracked or blocked outlet pipe can reduce filtration efficiency or cause irregular flow, which may affect water quality and overall tank stability. Replacing it with a correctly fitting C-500 outlet pipe ensures that your canister filter performs as intended and delivers clean, steady water back into the aquarium.
Made from durable, aquarium-safe materials, this pipe fits securely onto the Dolphin C-500 canister filter and is easy to install. It is suitable for both freshwater and marine setups, providing reliable long-term performance.
Keeping essential spare parts like the outlet pipe on hand helps avoid downtime during maintenance and ensures your filtration system continues running at its best.
