This was well timed! I was about to order another brand but this confirmed my 1st choice of the Hanna Calcium Checker. Please consider creating videos for the other Hanna Checkers as well and list links to them in the caption above.

Hi Kevin, Matt from Reef-A-Palooza | Orlando, many thanks for getting my Hanna Ph meter out to me. Also, super job on the video and will be looking for your next one to come out.. All the very best!

Love the test kit. All these steps are critical if you miss just one you get significantly different readings. I clean the vial before c1 & between c1 and c2. The only issue I have is with the unit turning off while prepping for c2.

OMG, seems like you have to be so precise in measuring - this will drive me crazy,

Thanks for the great video I wasn't following a few of the best practices.

Great video! Can you also do one for Alk and Phosphate (or any other saltwater testers you have) so we can make sure that we're doing the tests correct? I've been using these Hanna checkers for years and learned a few new tips just from watching this video!

I am getting consistently high calcium readings on Hanna checker, significantly high, compared to Red Sea and API. When added the powder the water sample to test then almost always is dark blue. What’s the problem? Thanks for feedback.

This is the most inaccurate checker they have.

Could you do us all a favour please? Could you redo the video with just the test steps, and not all the infill of the ins and outs of a ducks bum in-between each step. We don't need the info on the importance of calcium etc etc, we already have a calcium checker, therefore we know why....we have clicked the video link to see the steps on how to use it. thanks :)
