Owner's Manual

1. Verify riser tube position
**Most of our systems are sent out Pre-Loaded so this step can be skipped
NOTE REGARDING LOADED TANKS: Systems that arrive loaded will have the riser
tube in place and attempting to remove it will require the tank to be emptied and
refilled. DO NOT try to remove the riser tube from a loaded tank.
The riser tube sits in an indentation centered in the bottom of the tank. With the
riser tube properly positioned, ensure that it is within 1/3 inch (8 mm) above or
below the lip of the tank. If it is not contact us for help correcting the problem.
For tanks that were not loaded or Partially loaded:
1. Load media and gravelgravel goes in first
Make sure to cover the opening of the riser tube. Simply put something over the
end of the tube such as a piece of tape, to prevent anything from falling into the
riser tube.
If you have gravel with your system it will go in first!
Please note: MOST systems upgraded with a Vortech Tank do NOT require gravel.
With some medias (such as Filox/Mang-Ox) gravel is still required for the best
results, so if you have gravel, use it. Make sure to empty all boxes to verify it is
not in the bottom of the tank box or in a box with the media.
When filling the tank, do so slowly and ensure the riser tube stays correctly
positioned and centered in the tank. If you have more than one bag of media,
after gravel the order does not matter and all of it should be used. Once all the
media is loaded the tank will not be completely full, this is normal.
2. Finish filling tank with water Optional
Once the media is loaded you may finish filling the tank with water. Allow media
to soak for 12-24 hours. This can help reduce air bubbles, reduce initial flush time,
and ease initial startup.
