Do air lines get brittle and and crack when they age? Mine are getting a little hard and does that mean they need replaced? Is there a beeter product than the vinal stuff?
Yes, over time it tends to get brittle and weak. One common alternative to vinyl tubing is silicon, but I don't have any experience with the longevity of it.
Yeah they are kinda of a nuisance but my air pump are very noisy when I am trying to sleep but I put them on a timer so that my fish and I can get some rest.
