Pond Boss Forums GENERAL QUESTIONS Water chemistry Alkalinity... how much is too much?

Just wondering if there is a definitive point at which one much concede that their body of water is too alkaline? At this point based on the composition of my pond water/bottom I could probably point a flashlight at the pond in total darkness and get an algae bloom. I'm not complaining too much because the pond is quite productive and I get less then 18" of visibility with no fertilization... but eventually I'd like to be able to see something other then goldfish. : ) And I am afraid that this lack of clarity may at some point in time adversely affect the growth rates of my predator fish. Of course having said that I don't want to end up in some avoidable cycle of water chemistry changes. (As Cecil once pointed out to me... "if it ain't broke, don't fix it" and my pond water isn't broke per se.)

So back to what I was asking.... how much is too much in terms of alkalinity? Right now I read 180PPM+ with a PH of 8.1, O2 at 10PPM, No Chlorine, Bromine, Nitrites, Nitrates or Ammonia, and barely the register of any phosphates... (Perhaps <0.01 mg/l)... all read at 60 degrees F.
