Is it better to reuse the fluval or buy the blue filler that say strictly ejuice sells. I currently remove the filler in my 510 carts and replace it with the blue filler. I am not sure if this is the best way or not. I really don't want to use something not designed specifically for this purpose do to heating up something that could harm you.
What is the best filler to use.
Thx, Rob
