ok, so you did do some form of acclimitizing...

the water should be good in what way? there's still almost no biologic base...
it takes urine and poop to get that going... depending on the tank, this can
take weeks and the water will get pretty cloudy... leave it alone! it has to
transition... once the transition is complete, it will go clear by itself... i
generally use some feeder goldfish for this purpose... they are cheap and i
don't care if they survive or not... one can also get some fishing minnows...
they are even cheaper... i think $1US for a dozen... my last minnows lived 5
or 6 years before a long power outtage claimed them...
