Hanna Pocket Phosphate Checker

[InfernoST]

Does anyone have any experience with Hanna pocket phosphate checker because I just got mine today, I tested my tank water 3 times and the checker returned 0.00 phosphates (these are also the readings I get with the Salifert, API and Seachem test kits) so I tested my tap water twice and the tester return 1.73ppm for the 1st and 1.72ppm on the second so I'm fairly confident the tester is working.

What do you guys think?

Jarretshark has one Kieth. Btw, I thought it was called the pocket chicken tester. Lol, insider joke.

 

[InfernoST]

Thanks dude, I'll give Jarrett Shark a shout. It is a pocket Chicken tester, at least until I get to the hall for an eye exam.:lol:

I had the same thing happen the first time I used it just tested again today got a reading of 0.11

wow thats very low

 

[Mattl22]

Yeah that's why I'm so suspect of the reading although I have been vodka dosing for about 2 months I run Gfo and carbon and grow macro
So it could be right not sure

I'm running GFO, carbon and a sulfur denitrifier. I'll recheck it again today and see if it still 0.

 

[jadakiss]

can u explain a little how a sulfer denitifer work.

 

[stlblufan]

is it a phosphate checker or a phosphorous checker?

 

[InfernoST]

It says low range phosphate, and i did get identical readings on the tap water tests. Maybe at this point I have no phosphates. There are no problems at all with tank that would indicate there should be but I know the saying, there is no way you have 0 phosphates.

 

[stlblufan]

Just a note that the HI 736 model tests in ppB (and which has a conversion factor too) as opposed to HI 713 which tests in ppM.

Thanks, I have the 713. Should I have gotten the 763?

Tester Update

OK, I retested my tank water twice this morning and the meter came back with 0.00 phosphates (makes me happy). Not being content I took a cube of frozen brine and defrosted it in 60 ml of tank water, strained out the brine and tested the water, what a result, the tester returned it's highest value of 2.50 ppm and was flashing which indicates the concentration of the phosphate level is higher than the meters test range.
I believe I've come to a conclusion, that the meter is working properly and my tank has no detectable phosphates:shhh:. Another lesson learned (proof positive) is you must rinse out all frozen food with RO/DI before feeding the tank (which I do anyway), I had no idea the phosphate concentration was so high from just one cube.

 

[jadakiss]

i need to get my hands on that meter, where got it from?

 

[InfernoST]

I got it here http://www.eseasongear.com/hahi713chph5.html. I got the one with 100 regent packets. it was $65. The model is Hanna Phosphate Checker HI 713.

 

[jadakiss]

so if u have 0 p04 that means u have no algae?

 

[InfernoST]

Very little, I clean my glass once a week. I supplement algae wafers and formula 2 for Rocky my Lawnmower Blenny & snails.

I got the 713 check as well. It constantly reads 0 but when I checked on the Milwaukee meter, it reads .06. There's a .04 margin of error on these testers anyway. Good enough for me.

 

[kroman]

I have one as well, so far I think it's great before i starting using bio pellets my initial reading was 0.11 after 1 weeks with the pellets 0.09, 2 weeks 0.04 and 3 weeks 0.00 so i think it is working.

 

[InfernoST]

Cool. I'm thinking about going over to pellets myself, and the +/- .04 margin of error is fine by me as well.
