I have a quick inquiry regarding the Infinia 190 return hose I plan to utilize with my Ecotech Vectra L2. Are there any additional plumbing components I need to order? I do not intend to hard plumb at this time.

- Return hose barb fitting size: Red Sea typically uses 25mm (approximately 1 inch) barbed return fittings on their Infinia series tanks.
- Included with Infinia: Red Sea usually provides a flexible return hose and a barb fitting for the return bulkhead.
However, compatibility with your pump outlet is where you need to double-check.
- The Vectra L2 outlet is 1.25 inches (32mm) and includes barbed adapters and unions in its accessories.
What You Might Need:
1. Hose Adapter or Reducer
To connect the 1.25" Vectra L2 outlet to the 25mm (1") Infinia hose/barb, you’ll need one of the following:
- Step-down barbed adapter (1.25" to 1")
- Flexible reducer coupler (like a silicone or PVC coupler with clamps)
2. Hose Clamps
Essential for securing the hose to both barbs:
- Stainless steel (marine grade) or plastic clamps
- Size depends on hose diameter, usually 1" clamps for the Infinia side and 1.25" clamps for the Vectra side
3. Flexible Return Hose (if not using the Infinia-provided one)
- Reinforced braided vinyl tubing or silicone tubing
- Match the internal diameter (ID) of the fittings
Optional Components (Nice to Have):
- Ball valve or gate valve (for manual flow control, though the Vectra M2/L2 is controllable via Mobius)
- Check valve (if you want to prevent back-siphoning during power loss, though this is debated in reefing)
- Union fitting for easier removal of the pump
Summary:
You’ll likely need:
- A 1.25” to 1” reducer (barb or flexible)
- Hose clamps (2–4)
- Possibly extra 1” flexible tubing if you want to customize length
