I completed the project yesterday and I did with a 3inch
pvc T and a 3to1 bushing. i made it so it hangs of the side of the tank. The tubes just barely touched the stand. I hooked up 2 of them (3 inch X 24) on a 37 gallon tall. I have very slow flow threw them because it will be a sea horse tank. Im not sure if such a slow flow is good? also i filled it with rubble just to under the drain elbow. Does rubble size mater? mine was pretty small?
hot sure how much room there is for growth in the tube. If anything it will just be 15lbs more
LR in the system.
