No, I hot glued the tubing into the planter so that it cannot move. I
used zip ties to join the two halves together just like yours. With
mine the pump sit outside the contraption and pulls the water in
through a tube where the other end of the tube is inside the
contraption.

Hey Jan - this sounds like an interesting concept, as long as your pump
does not draw from the "slotted base " as mine does - I am going to look for
a pump with a "closed intake" system - much easier to to pre-filter this way
IMO - Thanks for the idea scs0 !
