i have carpet around my pool 1/2 deck. it's all black from the previous owner's neglect, and some of my own neglect. there's also green stuff on the metal railings, etc. i've been cleaning it with a pressure washer, seems to do a pretty good job.
the question is, i'm getting some splash back into the pool (which I think I JUST finished killing all the algae in)... do I need to be concerned with this creating an algae problem in the pool? moving forward, since i have the pressure washer, i will keep it from getting THIS bad.
