Yep that stuff is perfect. Any pulverized or pelletized non-hydrated lime will do. 1tsp to 1TBSP per gallon of soil. Either way it won't start working for about a month so if you know you are going to run into pH issues with your soil, like with Happy Frog being it's a very low pH soil, top dress with lime as well and be sure to ph your water/fed in properly.
