How Much and How Often

[Jacoji]

I'm used to a see-through tank where I can see the level of juice remaining. I ordered a SS tank for my ZAP and I also just ordered a Temon (for my Precise+ on order). I've been using the ZAP for a couple of days now, but haven't put on the SS tank.

If I can't see the liquid level, how do I know when to refill?

(apologies if this is a dumb question)

The vape will become anaemic before the tank goes totally dry

when i hade my DID i kinda guessed going by my other geni juice usage and would just a ml or 2 when a few hours went by, filling slowly and watching for possible overflow around the wick. its the only thing i dont like about non clear geni tanks
