Please don’t judge, I’m starting with a 3400/2.5 machine until I can afford a 4gpm. $1400 is no joke.
The proportioner inserts confuse me. With 3 gallons of 6.5 SH and Dawn, which insert is recommended for effective algae removal on 1.5 story siding?
I’ve commented on the formulation and simple mathbefore…use the search option for x-jet proportion/strength.
Generally the only proportioner you might use is the black one.
Now that I read Dan’s calculations, I’ll definitely use the black or grey insert. For some reason I had the white one in, probably could have safely drank that mix.
