It's not greatstuff brand, I forget what it is, but it's for ponds and stone. I like it because it's black so it's easier to disguize. If I don't totally cover some of it with coco fiber or sand, it won't stick out like a sore thumb.
When I can no more stir my soul to move, and life is but the ashes of a fire
When I can but remember that my heart once used to live and love, long and aspire
Oh, be thou then the first, the one thou art, be thou the calling, before all answering love
And in me wake hope, fear, boundless desire.
