If you mean frothy bubbles on the top of the water, these are quite
normal. If you mean the yellowish sediment on the bottom, these are
yeast sediment and normal as well. You could siphon it out if you
are changing part of the water and adding sugar. You can also add
a tsp of baking soda to neutralize acid and prolong the yeast
reaction time. If you are referring to a dense white mass which
floats on top of the water, this is probably colonization by another
bacteria. Throw it out and sterilize the bottle I'd guess. Maybe
make up a second batch a day or so in advance to avoid changing
the pH too much. Hope this helps!
