My Pond Chemistry
If the chemists can help me out here.... This is a 1200 gal pond, San Diego
area. Lillies are blooming! Water temp = 70 deg F pH = 8.0 NO2 = 0.3 mg/l GH = 18 KH = 11 NH3/NH4 = 0 mg/l (barely any color at all in the test vial) CO2 = 3.2 mg/l (according to a look-up table based on KH and pH) According to the kit, the only thing that's a little iffy is GH at 18. The CO2 was a bit outside the optimal range too. What are the implications of this? TIA!

The CO2 should gas off with aeration, I do believe. ~ jan See my ponds and filter design: http://users.owt.com/jjspond/ ~Keep 'em Wet!~ Tri-Cities WA Zone 7a To e-mail see website
