Hi Shelly,
IT could be that the wicks are stopped by algae. What r u using for wicking? Many times I have heard that putting a piece of copper into the reservior will help keep the algae down. Try putting a penny into the reservoir. Maybe you should also investigae a chemical substance to put into the reservoir. Pet stores carry algicides that people use in their fish tanks.

Are you using cotton or another organic fibre? If those, these will rot. Use anything synthetic, like nylon, even strips of panty hose.
I wick water, and I'm VERY lazy and neglectful & never have to replace wicks. Haven't used any chemicals either (except peterson fertilizer)
If algae is the problem, put the reservoir in the dark (inside a clay pot, or cover with foil).

I have been using 4 ply nylon string that I buy in the embroidery section at Wal-Mart. I thought it might be because of my hard water, so I started using distilled water. It's still happening with the distilled water. Guess I will check out the physan 20. Thanks for the replies!

Hi Shelly,

Yes, it's the algae that's clogging up the wicks. Once you take care of that problem they should last much longer.
