Is Tetra nitrate testkit reliable?

[spicyball]

Hi ppl, anybody here uses care to comment whether tetra nitrate test kit is accurate. I find the colour comparison chart easier to read as compared to salifert.

[Vinoth]

But make sure to divide the value you are getting by 4.4. Actually quite confusing. Salifert is straight forward.

[blacknails]

If used correctly, it is 86 to 97 percent safe.

Hahahahaha.... Sorry sorry sorry....

[lightningstrike]

what do u mean when u say divide by 4.4????

[terryansimon]

it means just that. divide the result by 4.4

[spicyball]

Any other experience with this test kit to share?

Can explain why must divide by 4.4?

[terryansimon]

because the instruction said so. for some weird reason. I wonder why too.

[Mellow]

The raw value u get from the chart is a measure of the NO3 ions. So dividing it by 4.4 will give the nitrate value in mg/l...hope that helps

Hope this answer helps you. Actually its not mentioned in the instruction sheet. Mentioned in the box. It would have been easier if they have mentioned in the instruction sheet. Missed this info for few tests and worried my nitrate level so high

[scanman]

realli??? divide by 4.4 .... no wonder my result always so damm high!!! arghh.......must go back to read the box

[lightningstrike]

me too.......

but if i m using 20ml of my tank water and the color resulting color has oredi overshot the color bar, it's written on the instruction sheet to add 15ml of ur tank water and then 5ml of distilled water. my question is where to get the other 5 ml of pure water??? mineral water can???? or tap water???

u talking about tetra nitrate test kit rite ??? i remember my tetra nitrate test kit onli needs 5ml water ..... not so complicated leh...

[terryansimon]

mineral water should be okay. its distilled water technically.

[lightningstrike]

hi scanman, i m sure u remember wrongly...... should be 20ml.

[Vinoth]

hi scanman, i m sure u remember wrongly...... should be 20ml.

i also use 5ml only. Is there are 2 versions of tetra nitrate test kit?

[Mellow]

I'm also using 5ml of water only. hmmm...might have different versions?

[Daniel-K]

me too using 5ml only. i better go and double chk again

[Daniel-K]

hmm.. double chk the instruction is mentioned 5ml only, but to divided by 4.4 is correct it only mentioned behind the box, Strength

[yus75]

hmm.. double chk the instruction is mentioned 5ml only, but to divided by 4.4 is correct it only mentioned behind the box, Strength

hmm....so where does lightninsatrike get the 15+5......

[Matt06]

I think lightninsatrike got the wong figure, anyway, it should be 5ml according to the manual.

[scanman]

yup confirmed 5ml ....& divided by 4.4 on box instruction ....sh*t .... all this while thought by nitrate high actualli is not .....why tetra ??? ...anyway quite pleasant to know ... now nitrate is not so high .... thks guys !!!!

[lightningstrike]

so sorry, i was referring to sera test kits!!!!! thousand of apologies!!!!

[Alentino]

but if the solution color turns deep red, it's still not that good isn't it? the maximum reading is 100mg/l on the chart where the solution is deep red, how do i tell if my reading exceeds 100mg/l? does the solution colour goes even deeper in red?
