[simple cherry question]

I appreciate the recipes,but won't that be a bit strong if my machine is drawing around 6 to 1 .

Wow thats some strong stuff. I suppose it depends on how strong your SH. I only use 2 gallons of SH in 5 gal pal with couple of scoops of Simple Cherry and works like a charm. I would like to know where I can get a SH test strips of some sort. Sometimes I pick up some SH at the pool place and stronger than hell can clean a roof with a 25-30 percent ratio and other times I have to make it stronger. They say it leaves the factory at 20 % SH then they say it should be at least 15% and they guarntee it to be 12.5%. I need a tester tired of just guessing...
