My Pond Chemistry

[stricks760]

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!

IMO, Put a little salt in the water ~ 0.9 lbs/100 gallons for the nitrite
(tha's NO2, right?) The CO2 should gas off with aeration, I do believe.
