An outstanding value for fresh or saltwater hobbyists, submersible pump Models 70-200 with variable flow control are great as in-tank water supply pumps for nano aquariums, refugiums, paludariums or for use as fountain pumps.

A clogged or dirty intake screen will greatly reduce performance. If the pump is used where debris has settled, raise it slightly to reduce the amount of debris contacting the intake. If slower flow is desired, use the flow control lever on the side of the pump or restrict the discharge flow.
Do not run the pump out of the water. Doing so may damage the pump. Always submerge the pump in the water before plugging it in the electrical outlet. It is common for air to be in the pump and tube when first plugged in. Continue to unplug the electrical cord and then plug it back in until water begins to flow.
Instructions to Convert Pump for Inline Use
*Models SP-290, SP-400, SP-530 and SP-800 Only
Unplug pump. Remove the front cover. Remove Impeller Cover with O-ring by turning counterclockwise and pulling away from Motor Housing.
Note: If Impeller End Cap remains attached to Impeller Cover when removing the Impeller Cover, it must be removed and reassembled onto the Impeller Shaft. Insert Impeller into the opening in the motor. Be careful, the powerful magnet may pull the Impeller very quickly and possibly injure your fingertips.
Position Inline Impeller cover with Arrow pointing UP, align the center hole with the Impeller End Cap and then press into motor housing until completely seated. Turn clockwise until it stops (about 10 degrees).
Ring Clamp must be used to lock Inline Impeller Cover in place. Loosen screw and nut on Ring Clamp and align slots on Ring Clamp with Fins on Inline Impeller Cover.
Note: Clamp must be installed with screw and nut in the "2 o'clock" position.
Make certain that:
Ring Clamp is oriented properly.
Ring Clamp is completely seated over the Impeller Cover and is secured tightly.
Note: The two protruding tabs located on the inside surface of the Ring Clamp must be inserted in the two slots on the outside diameter of the Motor Housing before tightening screw.
Care and Maintenance
Note: Always disconnect from electrical outlet before handling the pump.
To clean the pump, remove the Front Cover, Impeller Cover and the Impeller.
Use a soft brush, soft cloth or stream of water to remove any debris.
If scale has built up on Impeller or in the Impeller Chamber, soak in a solution of one part white vinegar to nine parts water, or Magi-Klean (#73696), for a few hours to soften scale and then use a soft brush.
For easier reassembly, moisten O-Ring on Impeller Cover with water before reattaching Impeller Cover to Motor Housing.
Remember: Monthly maintenance will add to your pump's life.
