Thanks Jersey,
I bought a test kit but it is one of the 5 way test and I am not sure how acurate they are.
according to the test everything is ok, the alkaline was a little high in the evening but I read somewhere that it's normal for it to rise when the sun is up and the water warms.
I called a pond and hydrophonics supplier and they said they had never heard of anything like this before, because the bubbles are sticking to the sides of the pond and not floating on the top.
I am going to see if I can find somewhere to test the water, I am on a well free of chemicals but you never know.
Anything anyone can think of I am willing to try.
This is just crazy,
