Nutrafin Gh Test Help

[arash53]

Hi Guys,

I lost my Nutrafin Gh/KH Test kit instruction, could anyone help me out how to use the test kit.

I have measured GH and the colour changed after 20 drop , whats the calculation for this test kit on KH and GH?

Thanks,
Arash

This should be it

For GH multiply by 20 to get GH expressed as Calcium Carbonate equivilent in ppm.
eg. One drop=0-20ppm as CaCO3,2drops =20-40 ppm etc.

For KH,multiply by 10.

Hi Arash,
I don't have the Nutrafin test kit but I have the Hagen one, and maybe it's similar because Nutrafin is a Hagen product, I think.

Instructions for gH: Add one drop at a time to test tube, insert cap, shake. Count drops and stop adding drops when the colour changes from pink to blue.

Multiply the number of drops by 20 to determine the general hardness in mg/L (ppm) as calcium carbonate.

0 to 60 soft
61 to 100 slightly hard
101 to 200 moderately hard
over 200, very hard

There's a conversion chart to measure it in other ways: multiply GH mg/L calcium carbonate by .056 = dH or by 1 = hardness

Edited to add: Thanks, Innkeeper! You jumped in with the info while I was slowly typing it out. What a nice community!

So 20 Drop means 400 which is very very hard and I should make it soft by water change right?

Here you go:
KH/GH (Nutrafin) instructions ???

The question is :

20 drop x 20 = 400ppm , for the shrimp tank should lower it to 250?

[Morainy]

I can't advise on what the right gH is for your shrimp, but if you lower it, do it slowly unless it was accidentally raised (by spilling Replenish into your tank, for example). Your shrimp have probably adjusted to the gH you've got them in.

My glosso also not doing well , could it be something related to the hard water ?
I bout these shrimps on Friday and I had one death since I add them , others just doing fine same as my pygme cories

My shrimps died over time, they usually don't die right away. How many did you buy?
