Havent heard of calcium blocks, what are they, are they easy to use and
control the calcium levels with??

Calcium is running about 420-450. I add a pH/alk buffer in a 2 gallon drip
daily. That keeps my alk up, and then I use Sea Lab calcium blocks for the
calcium. That keeps calcium steady at 420-450. I think it has just been the
addition of the buffer daily that has caused the alk to rise. I have noticed
that it rose slightly from week to week, and would counter that by skipping
addition of buffer one day a week (my tank uses about .20 meqs of alk per
day). I had recently switched products. I think the new product is a little
more effective than the other and thus caused the alk to rise more than I
expected. When I did my test this weekend, it was higher than normal, but my
calcium was still at 420. Now that the alk has gone down (back down to 3.6
over 3 days) my calcium is around 440ish. I have started adding the buffer
again, and am watching it to see how fast it causes the alk to rise back to
the 4-4.5 meqs level. Since this is acceptable, I am no longer worried about
it!
Thanks,
Shane

How is your calcium Shane, if my understanding of water chem is
right a low
calcium could cause alk to rise.

Thanks. I figured as much, and based that question on the assumption
that an
alk of 4.6 was way to high for a reef tank. Now that I am not
concerned
about that anymore, I have started my normal daily dosage of pH/alk
buffer.
My problem was I thought I needed to bring the alk down, and I knew
that
when I did so, the pH would drop as well, so I wanted to keep the pH
up
while the alk dropped. No worries now though!
Thanks again,
Shane C.

Shane,

without
affecting the
>alk?
No such thing. You mess with one, you mess with the other
too.
If you are having low pH problems, and have satisfactory
alkalinity
levels,
then you should be looking at gas exchange not adding
something else
to
"fix" the problem.
