I took my pond water to a swimming pool shop.......yes I know am I nuts?! Heck it was free. The PH was 7 and the alkinity level was 40. I'm currently fertlizing and the water visibilty using a string/white disk was 12 inches with a tanic acid tint. My question is can I trust these test to be correct?

Hard to tell. If they used the test strips, the alkilinty measure is suspect. If you only have 12 inches of visibility, why fertilize?

They didn't use test strips but drops/color code chart........I've backed of the fertilizer and taking a wait and monitor approach. Though I don't see any sign of a green hue to the water,It's more like coffee/tea.

I did the same thing and took it to a pool supply place and they ran a PH test for me for free. I also have an inground pool and asked the girl if the test kit that you take a water samles at home is accurate. She said yes and I asked her if she could call the company that makes the kit and ask about alkinity she did and said they were accurate on both. So we have been checking our lake with this method.

Lake,
Pond clarity does not tell you much about the need to fertilize, poor clarity may be due to suspended dirt, clay, etc.
There is a very interesting article on pond fertilization in the May June 2005 (latest with fantastic sunset..) issue of Pond Boss.... It suggests you actually determine which of the three nutrients your pond needs by setting up jars of pond water and adding one or a combination of the Nitrogen, Phosphorus, and Carbon components. It also mentions that when the current limiting or lacking nutrient is supplied, another may become the limiting factor.
I would think setting these jars up would be best done next to the pond.
I am sure there will be a lot of buzz on this site about this simple but ingenious concept and look forward to reading the input. I always though in NPK as fertilizer, does anyone out there know about the Carbon? What form would be best? Urea? Organic xxxx?
