Sorry, Doni, I didn't see your bump on this thread. I forgot about it.

I haven't notived any difference in the nitrate levels of the water using this product, however the clarity of the water is still very much improved compared to before adding the Purigen. The beads have darkened a lot more then the picture above in both the freshwater and saltwater tanks. I haven't tried to recharge the beads yet as I still see some white ones in the bundle.

I placed the beads in a stocking and noticed that the ones in the middle don't change colour so I'm attempting to find something that I could put them in that would allow for better water circulation around ALL the beads.
