Rainman, Ozark and Cecil, thank you all! No, I didn't use well water, the only water filling my pond is from rain and snow. There's no watershed at all. The pond was purposely dug on high ground to avoid muddy runoff. Cecil's photo does look strikingly like mine though.
I really like the idea of seeding that small moist strip near shore with clover and rye. That would have to help and it's an easy step. I don't know if I want to rip up any sod on my property, but it sure has me thinking.
The top soil idea is great too. How 'bout I just add top soil all around the pond and also on the inside bank? Then I can seed the whole area.
I'm definitely going to try the alum though. Even if it clears the pond up for just a few months, it will be aesthetically pleasing. Also, the first fish are arriving soon and I'd like the fathead minnows to be able to see each other to spawn.
Now I have to find a test kit fast to test my PH to see if I really need the lime. Any ideas on where to find a modestly priced kit?
Thanks again!
