Things You'll Need
- Empty 2-liter bottle
Instructions
Assembly
Construct the main filter with its protein skimmer and the skimmer pump. Place the filter unit under the aquarium or in another desired location.
Attach a siphon-overflow box to the pre-filter box and hang it on the aquarium rim. Place the siphon tube in the pre-filter box. Connect one end of the spiral drain hose to the slip-fitting on the pre-filter and the other end to the bulkhead in the main filter.
Attach the adjustable return spout to one end of the vinyl tubing. Attach the other end of the vinyl tubing to the return pump.
Attack the 1/4-inch vinyl tubing to the remote drain on the protein skimmer cup. Place the other end of the vinyl tubing in the 2-liter bottle for draining.
Operation
Fill the aquarium with water until it fills the siphon-overflow box. Fill the pre-filter box with just enough water to begin draining into the main filter.
Start the siphon. Add more water if needed.
Start the protein skimmer and pump once the water completely covers the pump. Continue adding water to the sump until the water line is reached.
Adjust the air valve that leads to the venture valves on the protein skimmer.
