Now that I have my water flow pumps I am questioning where their placement should be. I have two. I initially had one one one side in front of my Lr then another on the back of my Lr on the other side. After a few hours of that I got curious to see how much detritious would be blasted off my Lr so I placed one on each side of the tank blowing directly on my Lr. Now I wonder chich way I should go. Should I have them directed on my Lr or make a current flow around my Lr?
