3 piece airlock empty

[witchdoctor72]

Hello,

Newbie here: I'm brewing my first batch and 2 days into fermentation my 3 piece airlock is empty: is it safe to re-fill it?

Thank you for any advice from you master home brewers.

Yup. I usually have to refill mine a couple of times during primary. Either the fermentation pushed it all out the top or it dried out. Don't take it off, just remove the cap and pour in a bit more water, StarSan solution, or vodka to the fill line.

Cheers!

It's safe. Just fill it about half way and you're good to go.

thank you both so much for the help.

I was reading that temperature change could make it evaporate as well, I lowered the room air temperature from 76 to 70 after the first day, so maybe that was the culprit?

I used gin the first time around (didn't have any vodka) I hope that was okay?

cheers!
