added sludge digester,, now cloudy

my pond was just becoming, clear enough to see the bottom, still a green
tint, but could see down several feet.
I had a 'kit' of sludge digester,ultra clear etc.. so I used some of it,
since I already paid for it(found out about bzt afterward).
the pond has since turned very cloudy, been 2 days... still cloudy...
I cannot think of anything else I did to make it turn that way. all the
other pond tests are ok,, ammonia, ph, etc etc.
does this normally happen???
