[quote=ewest]My guess is the first test was wrong as to alkalinity. At least 20 ppm but 200 is optimum. [/quote

Hey Eric,

I retested today 3 times in spots out in the middle of my pond. Each one was right at about this.

Total ALK = was right near 40.
Hardness was right near 75
PH was about 6.8
My NT's and NTR's were both 0.
That seems to be a bit better than my initial test. I am still going to lime I think but at least it's not as bad as I thought at first!

The only difference between a rut and a Grave is the depth. So get up get out of that rut and get moving!! Time to work!!
