Directing return from canister filter
I have seen these black bendy things that people use to dirrect water flow coming into there tanks from return lines (excuse my use of excessive technical jargon) . What are these called and where can you get them from? I would like to attach it to a PVC return line coming from a caniser filter into the tank. Other sollutions for directing water flow in a sidways fasion would be apprciated.
Ted.
