nitrate level

[suvattii2012]

My no2 readings are 0 but the no3 is 40 and the genral hardness is higher at 160

[Terrance]

40 before or after your weekly water change?

FW, BW or SW?

[suvattii2012]

Fw and I did a 25% water change about 30 hours ago.

What's the nitrate of your tap water?

huh i never thought just to test my tap water, i think ill try that just to see the results!

[suvattii2012]

30 approx, i have never used these api 5 in one strips before. Im waiting for a new marster kit. The water in my area has got even harder aswell by these. These are the strips not the liquid kits.

Strips can be terribly unreliable

i dont trust the test strips. what is strange is that my lfs uses them, but petco uses the liquid test kit to test water!

[suvattii2012]

The strip said these readings but like you said bertie they could be out. In a day or two i can test proppely. Is the hardness any danger or the no3?

GH - 160
KH - 30
PH - 7.5
No2 - 0
No3 - 40

Do you have any spring water to test? Or any pure (not tap) water?

[suvattii2012]

Not on hand nope. I have some de-irnoised water in bottles for triops though.

[Pufferpunk]

Check against that. Nitrate should definitely be 0 there.

Yeah just did one and both no2 & no3 was 0

[bertie 83]

Hmmm. So the tests work.
