Ahhhh.....NOW it's much more clear

!!
THANKS! I now see the light

!!
I'll hold off on doing any more water changes and keep an eye on the levels and look for a drop in nitrates. Since the nitrites and ammonia have been unmeasurable for some time now, I think the nitrates will tell the big picture. Once I see that happen for a week or so then I'll feel better!
Thanks much again folks!
