Hi Ronald and Sharon,
It sounds like you've got a nice setup there, and that it's working the way it should. The 0 nitrites is perfect, and the high nitrates value probably means you need more plant material to use the nitrates.
You mentioned the bugs and I'm wondering if the plants aren't large and vigorous enough to be using up all the nitrates. I like to grow a wide variety of things in my grow beds so that if I lose one kind of plant, the others are still there. So I guess my question is: how healthy are the plants?
