MR1 Reactor installed with a dedicated
pump, returning water into the main
tank. This adds head pressure to the
dedicated pump, and may reduce flow
through the reactor. Do not submerge
the return to prevent siphoning in the
event of a power loss
MR1 Reactor installed with a dedicated
pump, returning water into the sump.
This is the preferred installation for
systems with a sump – the reactor faces
the lowest head pressure, and cannot
siphon from the main tank.
A simple installation where the MR1 is
plumbed directly into the main tank.
MR1 Reactor installed on the main
system pump, returning water into the
sump.
The MR1 is not designed to handle the
flow from large pumps – tee off of the
main return line and use a ball valve to
control the flow.

Insert the clear tube with the attached lower plenum and a
filter sponge into the MR1 canister.
Make sure the sponge is all the way at the bottom of the
canister, flush against the plenum – otherwise the media may
leak past it when filling.
We suggest using a length of pipe or tubing to push the
sponge in with.
Holding your thumb over the tube, pour your media into the
MR1. Be sure to keep the tube centered as you fill the
reactor.
Some media (such as phosphate control products) is not
designed to be aggressively fluidized in a reactor – please
read the instructions on your media carefully. You may fill the
reactor as far as you wish with these products.
For media designed to be fully fluidized, the reactor should
be filled no more than two-thirds full to allow the media room
to move around. With heavy or fine media, you may need to
add less.
Slide the second sponge and the upper plenum onto the
tube. The plenum may fit snugly, please use caution when
sliding it on.
Wipe any debris or leftover media off of the lid and top of the
reactor.
Press down firmly onto the center of the reactor, seating the
tubing into the fitting on the underside of the lid.
Twist the reactor lid clockwise and gently tighten the thumb
screws.
(Please do not get your hand stuck in the
MR1, it’s far harder to cut off than a Pringles can…)
