Let's talk about the hanna meters....

Not a problem at all. Life happens.

Man I will try tonight sowellj.... Just working non stop and barely feed the tank lately lol....
I go in a 4am and work till 5pm then off to my sons baseball untill 9pm and do it all over the next day...:( guess I shouldn't complain good money right before Christmas lol...

 

[sowellj]

Well ... I pmd the Hannah rep but no response. I was hoping to get some feedback/dialog started on these units.

Here is the regent I got....

I assume these Reagents are okay to use with the Hanna checker?

 

[thewackyreefer]

Got the Alk checker, wish I didn't waste the money. Doesn't work worth a ****, not even worth elaborating.

Yes - they are.

Hanna is coming out with new, liquid reagents to use with their ALK testers. They are swapping out for free the reagents that people already have:

So, seeing as how the powdered reagents measured alk lower than it actually was, and the cuvettes leaked, Hanna has taken care of the shortcomings and I am now glad to say that this checker is well worth the money. I had to go through some headaches, not to mention testing my patience but it has paid off.

The alkalinity checker now has liquid reagents, new cuvettes with caps that don't leak and a much much much quicker testing process. There is no more 2 minute timer, no waiting or shaking the cuvettes, and no under-valued alkalinity measurement.

The process goes.... add 10mL of tank water into the cuvette, put into the checker and press a button, take out cuvette and add 1mL of testing solution, invert 5 times, put back into checker, press button again and voila your alkalinity is displayed. I love it and am happy I was patient and didnt send the thing back. I tested against a Salifert kit and it was dead on so I am very confident that it is now not only precise but accurate

Just thought I would share.

have they fixed the phosphate or phosphorus checkers yet, i have been waiting for them to get fixed so i can order an alk and phos!

 

[melev]

Nice update subielover.

Yea when will they fix it?? It always reads 0....

 

[Dr.Venkman]

One of the better threads I've read in awhile! I hope that as more of newer alkalinity checkers get out there that people can post their results. The alk tester was on my christmas list, if I find it under the tree we'll see if it wants to behave. Merry Christmas All!

After receiving the new liquid reagent I withdraw my statement above. Works like a charm! Darn powder.

 

[Troylee]

Good to know guys... I hope they do something with the po4 checkers...:(

 

[ruppertb]

do we have any update on if the phosphate or phosphorus checkers have been fixed or if they claim they work better yet?

I would really love a better way to check my PO4 and cant wait for this to be accurate.

 

[Pizzapro83]

Whats the deal with PO4??????????

 

[ruppertb]

I am debating which one to get, phosphate or phosporus. but i dont know which one has been deamed more accurate/better

 

[Sea MunnKey]

Funny how Hanna hasn't said anything to confirm of any changes to their Phosphate meter problem? This is pretty unprofessional from a business stand point IMHO.

If Hanna can confirm whatever needs to be replaced then this thread wouldn't drag on & on and plus I don't have to read this far to get a "No Response Still" from Hanna ... sad :squigglemouth:

[Troylee]

there not gonna respond because the meters are perfect from the side....:( as long as they are selling there not gonna address the issue at hand....when the money stops pouring in they will start looking for answers and hopefully give us some answers....

 

[ruppertb]

ok so how did you all get them to fix the alk one?

have they been alerted that some ppl thing there is a problem with the po4?

I got mine and it is giving me a reading of 300 ppm, or 16.8 meq/l. My salifert test says 8.5 meq/l and the powder reagent Hanna says 225 ppm or 12.5 mel/q.

corals look fine and healthy. I am considering going back to API testing......
