Sanitizing spa flex question


New member
Everyone, I just recently picked up some spa flex PVC tubing for the connection going from my return pump back into my display tank. What is the best method of soaking this tubing in order to sanitize it? Do I use a bleach solution"¦ Or a vinegar solution?

The reason why I am asking is because I obtained this tubing from a local pool store and it's dirty. Any help would be greatly appreciated.
