Supports True Overflow Area with Fixed Water Plate 
How to Determine if the Overflow Area Has a Fixed Water Plate?
1.The fixed water plate is generally kept 1 cm apart from the bridge baffle, allowing water and debris from the bottom intake to naturally flow into the overflow area.
2.In fish tanks with a fixed water plate (flip plate), the overflow pipes can be easily removed without affecting the main tank operation.
3.If you are unsure about your tank’s structure, please take a photo of the overflow area and send it to customer service.
Types of Supported Overflow Designs:

•Fish tanks without a fixed water plate rely on overflow pipes to regulate water levels, so all piping components are glued and cannot be removed.
•These types of fish tanks do not support adaptive silencers. Please do not place an order.
