Went to a friends house a while back and he had a pvc mess in back of his tank. He said that it increased water flow. Has anyone got a link to this or have the real term.thanks in advance
 
It's possible that he had one or more closed loop setups installed on the tank that constantly circulate water in the tank. Search for Closed loop and see if that's what you saw.
 
The bigger question is "Are there better ways to increase flow?" and to that I would say YES.

When closed loops were popular, there were a very limited selection of flow generators available to the hobbyist. Now there are a wide range of propeller pumps both with and without controllers that move a lot more water for a lot less electricity. The monster pumps used on closed loops aren't as efficient at moving water as a propeller pump. Also, they are much harder to change as the corals grow and you need to rework flow to keep stuff from settling in dead spots.

Keep researching. Its a decision but there are a number of factors involved that may decided you one way or another.
