I have purchased a water hardness kit to test my tap water and i know that it is supposed to be less than 100 ppm in order to use it for CPs. My question is all of the tests i have come across test in degrees. Does anyone know how to translate the degrees into parts per million?
Ok so i use my test kit and the german hardness is 4 degrees. Which by that calculation would be just over 2ppm. That just doesnt sound right. I called my water dept and they said it is usually between 50-75. 75ppm being the max they have seen. It just doesnt add up. OR I HAVE GREAT TAP WATER, lol!
Where I live, I'm not sure if they can legally call the water "water." There's almost less water than dissolved particles. It comes out of the faucet as a slurry.
With 1 ppm = 0.056 German degrees, 4 German degrees = 71 ppm (4/0.056). So your test kit puts you in the expected range. Although you can use that for CPs, you should take every opportunity to run softer water (rain, dehumidifier water, air conditioner drippings, etc.) through the pots. I sometimes use tap water for Neps, but never for my Sarrs.
My water out here is around 100 ppm. I have been using it on all of my sarracenia for the past 7 years with no ill affects. We do get a lot of rain in the winter which freely drains through the pots, which might purge any built up minerals from the past growing season.
herenorthere, Yeah i figured out that i calculated completely wrong after i posted, was hoping no one would notice
Since my sarrs are in an outdoor bog they get plenty of rain water but i like to supp with a soaker hose that i have buried about 12" down. They seem to be growing well for my first year but i just wanted to double check my water companies figures. B/C for the last few years we get a decent amount of rain in may-june then a drought until sept/oct
Funny, I have maintained freshwater for 20 years now, mainly african cichlids and tankbusters(fish 2ft+) so i have never done a planted tank. However, that is why i just bought this new testing kit because i am going to do a 55 with injected co2. I figured since i bought the test equipment i mind as well use it for my cps as well
