Hi everyone! I'm having horrible problems with ecosoya CB Advanced. I use them for 3" container candles with essential oils. I used to use a CD 16 wick, which worked great, but recently it has not. So, I upped to CD 22. Now my wick starts out great, burns to the edge with a larger flame, but after about 7 hours, the flame gets much smaller, and on the 2nd light, the flame is very small. Why is this, and do you have a suggestion for a different wick? Thanks so much!!
