Bring the waterfall weir into position. The weir
has a return edge that will make it easy to
hold it against the waterfall box in the correct
position. Once in position begin driving the
stainless screws into place. Start with the top
screw on the left and right rst to hold the weir
in position. Continue driving screws into the
remaining pilot holes on the weir with your next
screw going into the middle hole on the weir.
Carefully trim out the section of liner inside of
the waterfall area to open the channel where
the water will ow through.
Use the remaining silicone to run an additional
bead along the joint where the waterfall box,
liner, and weir come together. Smooth out the
bead using your nger.
Install Filter Media
Position the lter mat(s) horizontally in the
bottom of the waterfall box. The Elite Waterfalls
include two green Matala Mats.
Fill the media bag(s) with biological media (not
included) and position on top of the lter mats.
We recommend using Bacti-Twist media in the
media bag(s). However, it is best to stand the
green Matala mats vertically in the box and
add in additional mats to ll the space (in this
case you would not use the media bags).
Pre-Cut Matala mats are available for the
14” & 22” Elite Waterfalls from your Blue
Thumb Dealer.
