Thank you for your comment Dave. I have been checking my water at my local commercial pet/fish store. The other day i checked my 2+ month old 29gal quarantine tank, 10gal 1/2 full comet fry tank, and the 20 day old re-do pond with goldfish feeding. All test didnt pick up anything any ammonia, nitrite, or nitrate which doesnt surprise me with the pond at all but the two tanks in the shade on the deck should read somthing, figured the test were bunk or expired ill still go and check another week. Hopefully the gravel filter will be enough until i can set up a large waterfall bio filter and flow that to the top river then off the fall into the bottom pond.
