HANNA PHOSPHORUS CHECKER

[jose hernandez]

so i was having problems with my 713 hanna checker always reading 0 so i went to a lfs store and purchased the 736 ulr phosphorus by mistake cant take it back becuz i opened it and threw out the box is this good or do i need the 774 ulr phosphate checker

You need 774...

736 read 0-200

774 reads 0-0.90

Not really, the 736 works just fine. To convert ppb phosphorous to phosphate, multiply by 3.066, then divide by 1000.

So if you get a reading of 20 ppb, 20 x 3.066 = 61.32 / 1000 = .06 ppm phosphate

The 736 and 774 do the exact same thing, the 774 just does that math for you.

Ya you can do the smart thing hahahah

I am way to lazy to do that ;Hilarious

The 736 (ULR Phosphorus) is fine, and is slightly more accurate than the 774 (ULR Phosphates).

I wrote a calculator so you don't have to do the math with the 736, just enter the reading (0-200 ppb) and it does the math for you: http://larryl.emailplus.org/fish/test-kit-calculators.html

[jose hernandez]

thank you

I’ve used 736 for the past 7-8 years. No problems at all.

 

[jose hernandez]

ok so i just did the test got 15 according to the chart sleeping giant gave me by the way thnks its 0.046 so is this high or low

 

[Sleeping Giant]

Bit high from what I have read, mine was 13

That’s good. I shoot for .05

 

[jose hernandez]

still don’t understand the number 0.046 is it 0.046 meaning it’s high or is it 0.04 meaning it’s low I’m used to my regular checker not sure if I like this one a bit complicated

 

[hllb]

I suppose it depends what you’re aiming for. To me that’s quite low.

You also don’t need to do math. Just use this reference chart: https://www.hannainst.com/hubfs/006...phate-conversion-table--hanna-instruments.pdf

I bought the ppb (that tells me anywhere from 0-30. Then again I had 0 and was having issues so i had to dose. It was pretty convenient to be able to check a few days after dosing you see exactly what stayed.

Do you have an apex? If so it will auto covert and log it for you. I use the ulr phosphorous and just plug in the indicated value...no math needed.

 

[jose hernandez]

yes i have a apex i will try it
