GH and KH and shrimp?

So today i tested GH and KH.

GH said to multiple the # of drops by 20.. 4 drops = 80
KH said multiple # of drops by 10. .9 drops = 90

When i'm looking at specs for shrimp they say GH 1-4.. is this drops? or an excessively low GH?

Same goes for KH. specs are low (which would seem more like drops, not results?)

Am i looking at this the right way?

sort of high but depends on what the mfg states. also are these results measured in PPM or by another?

Its a hagen/nutrifin test kit. Says 61-100 is slightly hard. My test said 80 (by counting drops)

Its still not making much sense to me (atleast versus any of the results i normal see posted.)

Found it!

KH/GH (Nutrafin) instructions ???

so if i multiply it by .56

GH = 44.8
KH = 50.4

No do those numbers sound right? If so its off the charts for shrimp

You multiply by 0.056; you are off by an order of magnitude.

To convert from German degrees to mg/L (ppm), multiply by 17.8. To go the other way, divide by 17.8 (or multiply by the inverse, which is 0.056).

Also, regarding your kH, I am unsure how you managed to measure 0.9 of a drop, so I would interpret your results with caution.

That makes a little more sense.

so 4 X20 = 80 * .056 = 4.48 GH
and 9*10 - 90*.056 = 5.04 KH

Those numbers seem make a little more sense. Than you for explaining that!
