Hit Or Miss

Better than nothing, but not much better. Hit or miss if it will kill moss and performs poorly on algae. Used on lava rocks in fire pit that had moss. Even on the same rock some of the moss died and some didn't. Used a few heavy applications. Same with algae on fence and on the ground. The Lilly product seems be more effective.
