Pond Boss Forums INTRO Questions & Observations water sample results

I sent UF a sample of dirt that came from one of the piles left for us after pond was dug. The dirt in the pile is like dirt at pond bottom. Sample dirt came back PH= 4.36.
I also have water test results that say:
PH=5.0
Total hardness=17
Total alkalinity=17
Total ammonia=.36
So, expert ponder's what now?
My calculations have pond size at .159 acres and average depth of 6.55 foot.
