What to use for filler to carts?

[TheRealJ]

So so the standard carts that come with the 510's, I hate that filler and it always burns on me casuing a nasty taste... Whats the best alternative?

Lots-o-thread on this. Most have gone with the fish tank filter material (blue). Just be sure it isn't treated for algea or other fish tank helpful stuff as it probably isn't the greatest to vape.

EDIT: some furnace/vent filter materials are just as good too

i've had good success with the polyfill from walmart.
you can get a couple years supply for a couple bucks.

other people use lipton tea bags, or blue foam from the pet store.

supposedly those are better, but the walmart stuff will do fine.

Yeah I tried looking for the threads. Can the blue stuff be bought seperately or do I get a fish tank filter??
