I maintained my no3 @ 3ppm (sulphur denitrator) and po4 @ .03 (lanthanum chloride)
I sample my socks every change under the scope and can't find dinos, I also let the bucket stand for awhile when I vacuum the sand and sample it at the bottom, middle and top and nothing.

Some of it could be diatoms the more I think about it. However, there's still some dinos.
I've had dinos and cyano for months. The cyano actually went from being purple to green and I thought it was actually green algae but it was matted like Cyano and turned black as soon as I dose chmiclean. I did not remove it first. I killed it, then sucked it all up via water change. Perhaps that caused a mini cycle. Snails are all over the brown stuff however.
