This week's tip:
I use a Film solution so the pump is built in. You might want to try this. But have had to use J&J in a tight before.
Get you a medicine measuring cup like that comes on the top of the Ny Quil bottle. Do your counting thing or however you measure. Look at how much is in there. Go from there adjusting your solution down or up as heat/humidity needs. Then you can mark a neutral solution and go less or more from there.
Didn't know if this has been up before, but I've never heard anyone doing this. Hope this helps a few.
