PH & Phoshate questions?????????????

[reaper]

My good friend owns www.reeferrocks.com , I am not endorsing his product
here, but was reading the overview and history, on Florida Aquaculture
Live Rock, written by a biologist named Sandy Nettles,
http://www.snettles.com/, Sandy nettles wrote the info on this page,
http://www.reeferrocks.com/liverock/history.htm , if you scroll half way
down the page you will come to a graph and look at the PH and Phoshates
of the different rock, my questions are could low or a high PH be a
result of the buffering capabilities the rock?? could hairy algea be
caused by phosphates leached from the rock?

I would like to know if my thought processes are going in the right
direction or is it the beer?

"my questions are could low or a high PH be a

There will be little leaching of Phosphate from one of these if it a fresh rock. Most of
the Phosphate leaching comes from the Phosphates left being by organisms on "real" live
rock. This is limestone, which will leach much less than "real" live rock.

Buffer, well the higher pH would do a little better at buffering, in the beginning. Once
it has spent some time in the tank it won't make much difference which one you use. The
rock will become coated with organic films, thus becoming more or less impervious to
acids, which would dissolve them.

The rock itself is fine to use.
