Yesterday I made my routine SW
mix with Reef Crystal salt as I normally do to 1.009 for hyposalinity treatment. I then added Kent Marine Superbuffer-dkH
to buffer the pH. This is the first time I used Kent for my SW
mix. I have been using Seachem until it ran out. I normally dose Kent directly to my main tank. I then leave the SW
to aerate. A few hours later, the SW
has gone very cloudy and appears to be calcium precipitation. There is a very fine layer of white powdery stuff covering my PH
My questions are:
1) Why would calcium precipitation take place when I am only mixing to a SG
of 1.009? Calcium should be pretty low at this SG
and should not precipitate.
2) This seems to be a problem with Kent and not Seachem. Am I using Kent correctly for SW
3) Can I still use the SW
if calcium has precipitated?
