Sounds like it--or some other organic. Evan's advice is pretty good--but the trees are news. You need to run your chlorine up to 15ppm--with the distilled water method mixed 2parts distilled to 1 part pool the WalMart test will reach 15ppm. Use 4 1/2 to 5 quarts of Ultra bleach (6%) to raise it there. Or use 5 1/2 to 6 quarts of regular (5.25) bleach. Either is fine. Test the water 2x-3x/day and raise chlorine back to 15 when it drops (anything from 12 to 15 should be OK, but below that, add).

It may take a few days to get results.
