Fireguy... did you ever figure out your dust particle situation in your water column? Your explanation describes my situation bang on. Thanks!

What kind of salt are you using?

[CpBizz]

Avitro Salinity by Seachem.... upon further research and salt research... I'm finding some have pointed their finger in the direction of this product. Would you say the same? And if my memory serves me right it began happening after a 15% water change. I do shake the salt bucket to hopefully ensure even distribution of salts etc and follow directions and ensure proper aeration etc.
If this is the culprit, which brand of salt are most using nowadays? I'm sure there is a thread for this. I shall look and see.
Thanks for the help!
