  • Take your new Eshopps AZU out of the box and confirm you have all the parts as shown on the parts listing. Any missing parts must be reported within 48 hours of purchase.
  • Place the Sump (#1) so that the side with the Eshopps logo is facing you.
  • Put the Cover Lid (#6) back on top of the Micron Bag Compartment, so that only the 1-inch Bulkhead hole will be showing.
  • The Square Foam (#5) should already be in place between the two dividers at the right side of the tank. If not, place it there.
  • Insert the 3-foot Flexible Hose (#3) into the Bulkhead Fitting and connect it to the Overflow Box on your tank.
  • Double check to see if the adjustable water height in the Skimmer Compartment is at an optimal level to ensure skimmer performance.
  • Take out the Removable Tray underneath the Foam to place any heater or media in the space below. Afterwards, place the Removable Tray and Foam back on top.

Frequently Asked Questions
Q: When replacing the Micron Bag, why does my skimmer overflow?
A: To avoid the skimmer from overflowing, the Micron Bag should be soaked in RO water for up to one hour. If the Micron bag is replaced without soaking, it will cause the skimmer to overflow. The bubble should dissipate after a couple of hours after putting it back onto the system.

Q: How often should I change the Micron Bag?
A: The Micron Bag can be cleaned, washed, and reused up to 3 times, then replacing the Micron Bag. The Micron Bag should be cleaned with water only (do not use detergent).

Q: What should the water levels be in the Return Compartment?
A: The water level should be 5.5 inch or 1 inch above your return pump.
