fishman, Thanks for the reply. I have used tons of test kits over the years, but will give this one a try b/c 2 ppm is better than 4 ppm in the 10 to 20 range. Harvey, Southern Excellence is a pond fertilizer... check you POnd Boss Mag. However as stated in past post it is way more costly than water soluble 10-52-4 pond fertilizer.
