• Welcome to ScapeCrunch!

    We are a friendly, online community of people interested in planted aquariums. We support and help each other learn and grow. It is our sincere hope that you will join us and find our tight-knit community valuable and fun!

    ScapeCrunch is different than Facebook Groups. Here's how:

    • It is a place where you can make long-term friends in the planted aquarium hobby and have long, multi-day talks on specific subjects.
    • Unlike social media, online communities like ScapeCrunch are much better at curating collective knowledge and in fostering deeper relationships.
    • They lend themselves better at long-form discussions.
    • You can maintain a thread on your personal aquarium with pictures and details. Other members can comment, help and ask questions. You can do the same with their Member Tank threads.

    Where Facebook is more like a large city-wide party, ScapeCrunch is more like your neighborhood bar "where everybody knows your name. And they're always glad you came." It's always fun to go to large parties but it's at the local bar that you feel people really know you. The great part is that you can and should go to both!

    Please consider joining to become a full fledged member of our growing community of planted aquarium obsessed enthusiasts. Let's grow together!

Well I’m trying to test my un gassed ph . I removed a water sample from my tank and added and air stone . 24 hrs later I tested my ph in the sample with my Milwaukee meter . I got 6.74 which is high for my norm . Then I turned off air stone and waited 2 hrs and re tested . Now the ph of the sample is at 6.05

Which of the numbers do I trust and why ?

Thank you
Casey
 
That's a little strange. Normally once it's been degassed, it's been degassed. When was your probe last calibrated? Do you have an alternate testing method to test the probe against?
 
I do I just need to calibrate my new pH tester

I have calibrated this Milwaukee pH probe only about two weeks ago.

Thanks for the details I’ll go ahead and get the alternate pH tester set up was just trying to get it done with what I had set up currently
 
Ok I calibrated my apera ph 60

Ungassed ph 6.13
Ph after 1 hr lights on 4.86 ( at this point I missed my timing of lights on )

Sincerely
 
So it appears that letting the aeration settle for a while is important to testing your un gassed pH at least from what I have figured from this little experiment.
