LINLAN 304 Stainless Steel Lily Pipe Inflow and Outflow with Mini Aluminum Alloy Pipe Holder, 360° Rotatable Outflow, Fits 16/22mm(5/8" i.d.) Filter Hose, for Rimless Aquariums (16mm-with Skimmer)

Skimmer Model Operating Parameters:1.Suitable for rimless aquariums. Installation may be limited if there is a cover.2.Recommended aquarium height: 30cm or more. Minimum aquarium height (without substrate and potential skimmer issues): 21cm.3.Minimum operating water level: 7cm from the top of the aquarium.Non-Skimmer Model Operating Parameters:1.Suitable for rimless aquariums. Installation may be limited if there is a cover.2.Suitable for aquariums of all heights.3.Minimum operating water level: 22cm from the top of the aquarium.Skimmer Rotation Adjustment Guide:1.Rinse the acrylic skimmer with tap water. It may have mold release agents on the surface, which can create a hydrophobic effect and make rotation and adjustment more difficult. If you skip this step, the acrylic skimmer may need to be placed in the aquarium for some time before achieving optimal rotation. Don’t worry, this is harmless.2.Ensure the inlet pipe is vertical to the ground without any lateral pulling forces. Additionally, the stainless steel pipe should be parallel to the side of the aquarium.3.Rotate the flow adjustment valve at the bottom of the inlet pipe to reduce the inflow at the lower grid, increasing the suction power of the skimmer at the top.4.Gently press the acrylic skimmer to allow water to flow through the grid. When you release your finger, the water flow should enter the grid. If there is no flow, try further reducing the inflow at the bottom or increasing the filter pump power.5.If there is no water flow through the skimmer after step 3, it indicates insufficient pump power. Consider replacing the pump with a higher power model or lowering the water level. Since parameters like filter pipe setup and pump height vary between aquariums, we cannot specify the minimum pump power needed, but we ensure that most mainstream filter canisters and pumps can drive the skimmer effectively, often with plenty of extra capacity.6.If after completing all the above steps, water flows through the skimmer grid but the skimmer does not rotate, consider re-adjusting step 2. You can loosen the screws of the holder, hold the end of the stainless steel pipe, and try different positions and fine adjustments. If rotation conditions are met, then tighten the screws.7.Monitor closely during the first 30 minutes to avoid the intake of organisms due to anomalies.Skimmer Notes:If the skimmer does not rotate but water flows through the grid, it indicates that the skimmer is operational and can effectively remove surface oil from the aquarium. You may contact us for assistance and advice on adjustments.Precautions:1.The connection part of the skimmer model has welding marks and is not rust.2.This device is not suitable for juvenile fish.3.Be cautious of organisms being sucked in while adjusting the skimmer.

• 【304 Stainless Steel】 The Lily Pipe Inflow and Outflow set is made from premium 304 stainless steel, ensuring excellent stability in freshwater environments and safe for aquarium inhabitants. It is robust, maintenance-free, and resistant to aging, offering long-term durability. Please note that this set is not suitable for use in saltwater aquariums.
• 【360° Rotatable Outflow】 The outflow Lily Pipe can rotate 360°, featuring an internal swivel design without protruding connections. This enhances the overall integrity of the outflow Lily Pipe, making it both simpler and more aesthetically pleasing.
• 【Mini Holder】 The included holder is a mini aluminum alloy clamp designed for glass up to 12mm thick. Its compact size features anti-overflow grooves to prevent dirt accumulation. The clamp is equipped with various sizes of hidden screws and hand-tightened screws, ensuring optimal concealment and a secure fit on different glass thicknesses.
• 【Rotatable Skimmer】 The included acrylic skimmer can rotate when properly adjusted, which helps surface debris flow more smoothly into the filter and prevents debris from attaching and blocking the surface skimmer. The elevated grid prevents aquatic life from being sucked in. For detailed adjustment methods and precautions, please refer to the instructions below.
• 【Package Includes】 1 x Stainless Steel Inflow Pipe (with flow regulator at the bottom), 1 x Stainless Steel Outflow Pipe, 1 x Acrylic Skimmer, 2 x Aluminum Alloy Clamps (with mounting accessories).
