How come my calcium stock solution has some brownish particules at the bottom of the container after a few days? It was clear when it was first made. I used the dow's pellets.
hmmmmm... could be just that the pellets were dirty for lack of other words... i think there was a problem even with someone using a batch of dowflake that they would get a brown film uptop after mixing... i would say the pellets contain some dirt from production......
is this the 1st batch of the pellets u are doing or has this happened before...
