I went bought the big 50 lb bag of lime this weekend at the hardware store. Man, 50 lbs if a lot freakin lime. I filled a 5 gallon bucket and good size box but for $7 you really can't bet the price. The mix ratio seem to be about the same as the Kent kalkwasser I was running. Well I won't run out for a while thats for sure. Any thing you have noticed that I should watch for?
