Instructions for Connecting Undergravel Filter Plates
- Lay out Undergravel Filter plates before placing in aquarium. This will help you determine which sections require openings.
- To open water flow partitions, use pliers to snap vertical seams first. Now fold entire piece towards outside of plate, bending along horizontal seam until it breaks off.
- Connect Plate Locking Clips to bottom of plates. Invert and follow remaining assembly instructions.
Easy Set-Up Instructions
- Feed air tubes through spout and attach airstone to bottom. Insert cartridge into spout. Insert the spout/airstone assembly into top riser tube.
- Insert complete riser tube assemblies into the filter plates. Twist the tube clockwise to lock it in place.
- Place completed unit into a clean tank and cover the filter plates with about two inches of washed gravel. Fill the tank with water using a bowl to diffuse the water.
- Adjust riser tube so that spout is just below water surface. Attach flexible airline (not supplied) to air tube.
Cartridge: The cartridges supplied with this unit remove harmful gases and odors from the aquarium. They slip easily into the filter spouts with no need to disturb the set-up. For best results, they should be replaced every two to four weeks.
Airstone: An airstone should be replaced when the airflow becomes sluggish. Tank conditions will determine the effective life of your airstones.
Note: With the plates connected, do not use airlift method on one lift tube together with a powerhead on another lift tube. Powerhead may overcome airlift power.
