Hi Robert,

I had this _exact_ same thing happen to my 10g planted w/ DIY CO2.  All
I did was 20% water changes 24 hours appart until the water remained
clear.  I have no idea on the cause, but I remember testing for CO2 in
grade school using very hard water (limewater I think) and seeing if it
turned milky.  My GH here in Toronto is about 10 dGH which makes it
medium-hard.  Since I have a lightly planted tank, and you have no
plants yet, this may be the cause.

BTW: I think I've given up on DIY CO2 faster than most on this list as
I'm looking to replace mine less than 6 weeks after starting it.
