My twin bulkheads sit 5 feet above the ground...The tank is 180...I already purchasd the PVC, but now I see how easy FLEX tubing can be used, especially for the return....Please give me a picture of where everyone stands on this subject by voting...BTW I spent about 30 minutes at Home Depot last night, configuring different sizes/shapes of PVC, I had fun....
...Flex tubing sounds really good right now....The filter is coming in tomorrow ....
