• Direct fit with our pre filter sponges
• Adjustable distance from back wall
• Black to blend in with backgrounds

Optimize your Marineland hang on back filters by swapping the intake. Switching from the square intake to ours allows you to run a pre filter sponge. This extends the life of your media inside the filter and adds extra mechanical and biological filtration capacity. Made to fit your intake, the angle keeps the pre filter away from the glass and off the bottom.
