Marc,
Nope, no additives. Auto water top off system of RO-DI. Salt levels adjusted
as necessary. Would it be common for the probe and test kit to be
consistentantly high together? I have checked the calibration of the probe
with 10.0 test solution and it checks O.K. I will locate a new test kit and
check it with that.
Thanks,
Dave

I doubt the reading you are getting from your test kit and the digital
probe are correct. It is simply too high. Do you use Kalkwasser to
replace evaporated water?

I have been running a high Ph level for about a year now. It averages
9.03. This level is by test kit and also digital probe. All other levels
are
where they should be, Ammonia - 0, Ni - 0, Na - 0, Ca 350 - 375. No
additives or supplements used.
I have a fairly complex setup. 120 gal reef with crushed coral base -
55
gal FO bare bottom - 20 gal refugium/6 DSB - 12 gal sump w/2
skimmers.They
are all connected. About 150# LR. I'm using RO/DI water supply. Any
thoughts?
Thanks, Dave
