Help!! Hanna Calcium Checker

Has anyone else had problems with the Hanna calcium Checker my readings are all over the place between 600 + that 280 does not get a consistent reading I watch the video I've contacted a Hanna they sent me an updated video and the guy couldn't even get the correct calcium count on his all I'm getting is a bunch of running around from Hanna how do you guys use the Hanna Checker and make it come out right

 

I utilize their di water, their curvette cleaner. Also go slow with the white titrator.

 

I bought the Hanna Checker for Calcium - shortly after it came out, about 4 or 5 years ago. I tried it once and sent it back. At that time the amt of sample water from your aquarium was only .1 ml - and in my opinion too difficult to get a precise reading. One of their suggestions at that time was to get a hypodermic needle - so I could have more precision on the .1ml. That didn't fly with me.

Have they improved the process since then ?

 

I also have had a terrible experience with the Calcium checker. I use their alk and PO4 checker all the time and they are awesome. But my Ca checker has spent the last few years sitting on the shelf. I believe I heard that they now provide a different syringe for measuring out the .1mL.

 

Make sure the vials are free of dirt and smudges, since it uses light to do the measurement.

 

I have had alot of luck.. I will write something up and do a video

 

I like the Hanna po4 checker and phosphorus checker. I haven' tried the alkalinity checker but I did try the calcium checker. I found it to be horrible. I will not use it ever again. Very inaccurate and different readings everyone.
I just use Red Sea and salifert kits.

 

Yes they added a pipette with the kit now. Still junk and hanna has nothing but excuses why it doesn't work.

 

Here is a video on what to get in addition to the checker..



and here is a video of doing the actual test

 

Any feedback? Have you all been trying it this way? Any other testing videos etc that people are looking for?
