Better to go with flexible PVC or tubing for the return pump so you don't loose pressure and then add the elbows (45 degree ones worked better for me) to the drain to get it to the other side.
I cleaned my skimmer this weekend inside and out, and since then I have had immense amounts of bubbles in the display. Everything is covered in bubbles. I am not a happy camper. Need to get a bubble trap.
