Clear Slime - What is it?

[Cloyd1980]

Hello all,

I have a ground mounted AC unit and an air handler/heating unit that sits in an outdoor closet next to the AC unit. Today I noticed a fairly good amount of completely clear slime (it looks like vaseline, but feels like wet slime) underneath the condensation drain pipe coming from the air handler. Does anyone have any idea what this would be?

Some sort of bacterial or fungal goo.
The condensate taps for the drain of all air handlers have two taps.
One is the low, primary drain, the second tap is for the "overflow" in case the first one becomes with goo.
I've seen so many idot professional installers not pay any attention to the second port. If no drain on the secondary port there needs to be one.
All condensate drains need proper traps, by the way, without a trap, you are blowing conditioned air out to the world.
Maintenance tip: blow out the drain:

At work the hvac dept puts tablets in the drain pans supposed to keep them clean but really not sure what’s in them
