Hanna Alkalinity Checker

[Lenny]

Has anyone used the Hanna Alkalinity Checker? Is it any good?

There was a big thread about the Hanna meters a while back and they seem to get mixed reviews.

I have no issues with mine now that they replaced the powder with the liquid reagent. So easy, quick and much more accurate that it used to be.

I got one recently ( the liquid reagent one) , I would say its that I am observing 1dkh variation wrt lamotte.

Lamottes read a little low than what it is actually so considering that the hanna may be about 0.5 dkh higher.

Considering the costs I think lamotte is still better.

That thread posted above is the first really bad things that I have heard about Hanna meters.
Most of what I have heard as been good. I do not nor have I ever used one, but thought they looked nice and easy to use.

I really like mine.

I really like mine to. I'm getting lower readings than I would get with other test kits, especially Salifert. (except maybe Lamotte which for me are really close give or take) I have recently come to the conclusion that previous findings, concerning recommended Alk levels for a given situation/set of paramaters based on the use of other test kits are higher to considerably higher than need be. I have always been under the impression, with excellant results I might add that I should maintain a Mg level of 1400 to 1550 and an Alk of a stable 10. These were par from what i've seen on many forums for a strictly SPS tank not using the Zeovit system. However I believe many of these previous recommendations were made using inaccurate tests that were really keeping our tanks at an Alk of around 8 dkh with decent results. I came to this realization after using my Hanna Alk meter to try and raise my Alk to 10 ( no, not to fast) where I thought it had always been and was supposed to be and ending up with un happy corals. All along I think we've been under the impression that our tanks need a higher Alk than they really do which can cause problems when switching to an accurate testing method. Just my thoughts and experience.

Cool info!

I'm leaning towards getting these two so I can compare!

Thanks for the info! I bought two Salifert kits and one Elos Alk test kits and the results are as follows 9.5 dkh, 15 dkh and Elos 7.5 dkh. After reading these test kits I'm so confused :squigglemouth: I'm going to get a Lomotte test kit and a Hanna Meter! :bigsmile:

I have one and have spoken directly with Pete at the Hanna tech services. Hanna Alk meters read 20 ppm LOW vs Salifert. There is a huge thread on RC about the Hanna meters and some are saying that Salifert test for Alk reads higher than what lab grade test kits show. IMO, if you keep your Alk steady, and in the middle (9-10) then you can't be wrong.

+1 for keeping it stable. Personally i dont care if it is off by .5 or one dkh. My experience is it reads close to what my other kits did...and that it is consistent. Through using it repeatedly i am convinced it is consistent and if it is off by one dkh i am not really concerned

I did a test yesterday with the same water with 2 new Salifert kits and one Elos Alk test kits and the results are as follows 9.5 dkh, 15 dkh and Elos 7.5 dkh. Definitely getting a Hanna Meter.

MY hanna and elos read almost exactly the same. I trust both and I have used lamotte with good results also. I would rate them as follows hanna, elos, lamotte and





























salifert...

I always use La Motte but know I've the Hanna Checker but with the powder. It's new, I only used once! Can I just buy the liquid reagent and use it, like this?

Yep, the liquid reagent can replace the powder with the same meter and it's much more accurate. Now if only I could sell all the powder reagent I have sitting around. Anyone want to buy a 100 pack of Alk powder reagent? :tongue:

 

[gqjeff]

Now if hanna would just make the po4 test powder a liquid. I have used the meter for 6 yrs and have hated the powder every time I have used it lol.

+1 The liquid reagent in the Alk checker is much better. We need the same for PO4

Hanna is replacing the powder reagent with the new liquid. You can go to their site and get it replaced. You will need your receipt though.

Do you know where to go on their site? I couldn't find anything. Do I need to email support?
