Apex pH Probe

Enigma · #1 09-04-2012, 01:41 AM

I'm waiting for pH10 calibration fluid in the mail.

I'm recording the Apex results as my pH, but I'm backing it up with my API test. My API test tends to show my pH a little higher than the Apex probe.

The probe records between 8.11 and 8.23. It took a little bit (couple of hours) for it to settle in. That first reading may have been erroneous.

I'm pretty confident in it. If it is out, it isn't out by much.

Adding water to a vial to test with a test kit will alter the pH slightly up. So it will read at least a bit high.
Testing pH will also make a person crazy, I highly recommend against it. My Apex pH probe is still in the box, right where it belongs

pH doesn't make me crazy. Ca/Alk/Mag do!

I don't test that either, not taking any chances!

I agree with Brad on this, ph probe will drive you crazy one day. I just don't bother calibrate or care about my ph probe reading any more.

Sounds like a plan.

I sleep much better when I'm not chasing numbers. I tested Ca once this year, it was good. Alk was a bit high, figured if I left it alone, it would probably level out. Corals look good, I was probably right.

haha im exactly the same , ok so did my first test in what ill say forever lol calcium 400 on the nose and alk 7.5 , i never tested ph

nitrates are 15-20 and i dont test for phos , i just run copious amounts of gfo lol

my salinity is 1.023 and the temp is whatever the room keeps it at

i have a crazy amount of coral and i do water changes with IO , def not as reg as i use to.

my next test will be spring when this converstaon happens again:P

and its not all about being a old tank or new tank my roomates tank of a month or two reads the same as mine.
