Exactly type of tubing do folks use for their chlorine pumps? And what longevity do you get? Any reason not to use the cheap black 1/4" landscape drip tubing - such as Raindrop? Both the landscape drip tubing and the Stenner "FDA Approved" UV black tubing are polyethylene - though it is possible they might be PE of different types or quality levels. The Stenner tubing is 10x the price of the garden tubing. Note I don't want to use something that will have a shorter lifespan and just create more work for myself replacing the tubing more often.
