Noticed Filter Sand in bottom of pool

When I vacuum I have noticed that I have filter sand at the bottom of my pool. I think I must be blowing it out of the return. I think I have a crack in the pipe that runs down the center of my sand filter, which I think is where it is coming from. Could this create a problem for me down the line, or would it be okay to live with it for the rest of the pool season? and of course fix it for next.

If you don't mind the sand in the pool it won't hurt anything.
