Just got in my new max and took it out for the first day of round 2. The foam marker is a richway mintrac(I think). Think I filled that thing up 2 or 3 times in an 9 hour day! I'm using water and a foaming agent I bought from my dealer. Mixing about 1-2 oz (or a couple of quick pours) in the 1 gallon unit. Balls are spaced out about every 6-8 feet. Am I doing something wrong? Does regular dish soap last longer? If so what rate and brand is everyone using?
