Pond Boss Forums GENERAL QUESTIONS Water chemistry Understanding water quality parameters

and how they apply to different facets of pondmeistering.

This year one of my goals is to get a firm grasp on all the different things that affect water quality in ponds, what to test for, and what can be done to adjust those test numbers.

I have a short list so far, would someone that has a better understanding than I do chime in?

Here's where I think I need to check, and where the numbers should fall:

Dissolved Oxygen - minimum 5 ppm to saturation.
Alkalinity - >50mg/L to 150mg/L
Total Hardness - >20
Calcim - 25 ppm to 75 ppm
Iron - <0.30 ppm
Magnesium - 5 ppm to 25 ppm
Phosphorous - 0.005mg/L - 0.05mg/L
Copper - 0.005ppm to 0.01ppm
pH - 5.5-8.5
Nitrogen - ?-?
Conductivity - 250-750
Turbidity (Secchi Disk) - 18" to 24"

What else am I forgetting, and are those ranges correct?
