I have been making my own CS for over two years.  I always make it the same.  I 
add H202 3% 1 drop for every 2 oz. of CS.  This has been working great.  Within 
15 minutes the CS is crystal clear.
Lately, when I add the H2o2 the CS turns very murky and it never clears up.  I 
have tried adding more H2o2 and still it stays murky.  I have no idea why this 
has been hapening.  I have been using the same steam distilled water all this 
time, but I am wondering if they could have changed something in the water.  
Does anyone have a suggestion????
