Spin Flow Nozzle

Spin Flow Nozzle Turn narrow return-line output into broader, rotating flow for healthier movement throughout your reef aquarium. The Stratiform Spin Flow Nozzle helps make your return pump more useful. Instead of pushing water out in one narrow stream, the internal spin geometry helps roll the flow outward into a broader rotating pattern. For coral, flow helps deliver oxygen and suspended food, carry away waste, and improve water exchange around tissue. The Spin Flow Nozzle softens harsh straight-line return flow and adds more usable movement without adding another pump to the display. Why Spin Flow Helps Coral Broader movement: Spreads return flow across a wider area instead of one narrow jet. Gentler contact: Reduces harsh direct blasting on coral tissue. Better exchange: Helps bring oxygen and suspended food to coral while carrying away waste. More useful return flow: Turns existing return output into part of the tank’s circulation pattern. Detritus suspension: Helps keep fine particles moving toward the overflow instead of settling behind rockwork. Compatibility Variant Fits 1/2 inch Spin Flow Nozzle 1/2 inch Loc-Line-style modular hose 3/4 inch Spin Flow Nozzle 3/4 inch Loc-Line-style modular hose Note: Choose the size that matches your existing modular return hose. This nozzle is not a threaded plumbing fitting. Design Details Internal spin geometry creates rotational return flow Connects directly to compatible Loc-Line-style modular hose Low-profile design with no extra pump, cord, or controller 3D printed for complex internal flow geometry Made from reef-safe TPU plastic Installation Turn off your return pump. Remove the existing outlet nozzle. Press the Spin Flow Nozzle onto the matching 1/2 inch or 3/4 inch modular hose end. Angle the outlet where you want broader movement. Restart the pump and adjust as needed. Flow Placement Tips Aim across the tank rather than directly at coral tissue. Use upper placement for more surface movement and SPS flow. For LPS and soft corals, angle flow around colonies instead of directly into them. With dual returns, point each outlet slightly toward the opposite side so the patterns interact. Specifications Product type Aquarium return flow nozzle Available sizes 1/2 inch and 3/4 inch Connection type Compatible Loc-Line-style modular hose Primary function Rotational return-flow output Material Reef-safe TPU plastic Manufacturing method 3D printed FAQ How does spin flow benefit coral? Spin flow spreads return-pump output into a broader moving pattern instead of a concentrated straight jet. This helps improve water exchange around coral tissue and carries waste and detritus away from colonies. Will this replace a wave pump? No. It makes your return flow more useful, but most reef tanks still benefit from dedicated circulation pumps. Will this fit threaded plumbing? No. It fits compatible 1/2 inch or 3/4 inch Loc-Line-style modular hose, depending on the variant selected. Is it reef safe? Yes. The nozzle is printed from reef-safe TPU plastic for use in saltwater aquariums. Will it reduce flow? Any nozzle can add some restriction compared with an open return outlet. The amount depends on pump output, plumbing layout, nozzle size, and system configuration. Which size should I choose? Choose the size that matches your existing modular return hose: 1/2 inch or 3/4 inch.
