I want to revisit a subject that has come up in the past, that probably no one cares about but me, my water hardness. :grinno:
So a few posts back I linked to my previous annual water quality report, and told you how I never used to read the printed ones they mail out each year. Well suprise, I got the 2010 report today in the mail, and I actually sat down and read it (for the benefit of the fish). I would seem that my area of Maine has very soft water. The report lists 150 ppm as the Max allowed by Maine law, but for 2010 my water is 9.5ppm. Yes, only 9.5ppm which is only like half of one dGH!
So, to make sure I wasn't crazy, I went online and found this in FAQ from my water company.
What is the hardness of my water?
Hardness levels in Maine waters are generally low but can range from near zero to several hundred milligrams per liter as calcium carbonate (mg/L as CaCO3), the standard unit for hardness. The Greater Portland water source (Sebago Lake) has a hardness value of 9 and is described as soft, as you can see from the following table.
Hardness Range (mg/L as CaCO3)
0 – 75ppm = Soft
75 – 150ppm = Moderately hard
150 – 300ppm = Hard
More than 300ppm = Very hard
I would say my water if VERY soft, which I have said before. I guess I didnt realize it was this soft/low. So, for the past two weeks or so I have been dosing GH booster (my own homemade version based on Mr. Barrs booster), at 1 tablespoon per week. I think I might have to increase this, I mean 0.5 german degrees out of the tap is pathetic. The goal most people list is 3-6 dGH, but I wonder if this is still the goal.
Iron is listed as < 0.05ppm, again way too low.
Calcium is listed as 2.8ppm and magnesium is 0.56ppm.
Lots of other things are listed, but you get the point. Also, I found this quote interesting, since I didn't realize Maine had such acidic water, and it has to be artificially raised.
Sodium hydroxide is added to raise the pH of Maine's Naturally acidic water...
