While I await my Waterbox 100.3 to arrive, I plan to purchase extra filter socks. This is the first system that I will have owned with a sump and filter socks. It comes with one mesh and one felt sock. I already ordered a spare of each when I made the initial order. However, after reading other posts, it occurred to me that I will likely need some extras, especially if I want to perform micro-bubble scrubbing, which I likely will after seeing some of the benefits.
