" Sarah thanks for your kind words "
I have just installed a Koralia #3 to bottom right side wall directed towards back wall...as the flow hits back wall and rolls down towards bottom sweeping all the crap out from caves thus doing the job I can't get at...after moving the swivel head a number of times in order to get the right water movement...cord from the pump has been hid between wave box and back wall...All in all it's doing the job.
