- You can hang it on the back, front or sides of the most sumps.
- You can freestand it on the base of a shallow sump with a water level below 200mm.
- You can freestand it on a box or shelf in deeper sumps.

- You can feed water from the top, side or at an angle.
- You can even pump feed it.


You MUST only use the 20mm bolt to attach the motor to the ClariSea as per our Quick start guide below. Do not use the 30mm bolt, (used for the clean fleece), as this will result in damage to the motor assembly.
