![]() Kh 9
Ca 420 Ph 7.6 I have calibrated both of my probes and this is what the result is. When I use my Salifert test kit it comes out at 8.2 I'm scratching my head here WTF. Should I be concerned? I see everyone elses Ph is 8.2. Should I try boosting it up and with what? I don't see anything on the Reef Calculator to do this with. |

![]() Yes, lots of polyps out but could be a little brighter and there is good growth.

![]() my probe was reading high and my ELOS kit said 8.3 the probe was a year old (they say 2 years is recommended for replacing) so I tried to re calibrate and still high readings i bought a new probe and now its reading what my kit says. I trust the test kit over the probe, but you should be able to read the probe # if your certain about the test kit result )sorta just factor in the difference when you read the probe ) also when you calibrated the probe did you let the calibration # really stabilize - i always find this hard - it likes to keep either falling or raising slowly, i was told to let it calibrate for a while to be certain. hope this helps

![]() Nobody's pH is anything exact. Everyone's pH fluctuates daily. Your's may be just a snapshot of a moment during the day. I would trust your calibrated probes much more than most other tests. Your measurement is a bit low, likely a morning test.

![]() It's 7.5 at lights out and 7.6 during the day. Is it a problem and how do I bring it up without affecting my other water parameters? Thanks

![]() start using kalk for your calcium and alk needs or used baked baking soda for you alk needs. Both will raise your ph.

![]() I have been following this thread as I have the same problem as well. I use "baked" baking soda for kh, but maybe I will try kalk and see if it makes a difference

![]() Dont mess with it ph probes are recommended changing 6 months to a year and much sooner if exposed to air. I would go with the test kit. My probe ready 7.6 and elos test kit reads 8.3.
