I recently got a bunch of new 4L tanks and noticed the sides had these new inserts in them that my old tanks didn’t have.
Curious what these are for? I’m guessing these mitigate frothing and/or splashing of resin, but would love to hear an official comment on them and whether there are other significant improvements over the older tanks (which I have no problems with honestly, except for frothing and splashing sometimes
)
