My damn mini split drain line clogged and flooded the whole wall

Had a Midea unit running fine for about 8 months in my 200 sq ft build near Portland. Woke up Tuesday to water dripping out of the outlet behind the couch. Pulled the inside unit off the wall bracket and found the drain line full of algae and gunk. Spent 3 hours snaking it with a piece of thermostat wire and shop vaccing the line out. Then had to cut out a foot of drywall to dry the studs and insulation before mold set in. Anyone else dealt with this and found a way to keep the drain lines from growing stuff?

Been told a little bleach in the drain line every few months stops algae, but I've been too nervous to try that.

Whoa, @taylor.paige bleach in the drain line sounds sketchy. Idk, I'd be nervous too, that stuff is harsh if you mess up the dilution or get it where it shouldn't go.
