Dirty IO salt

[whatcaneyedo]

For those of you who have never seen this before. This picture shows the upper water level line in my water change brute trash can. I use an RO/DI system that has always tested between 0-1 tds. I've mixed 2 buckets of Instant Ocean, 2 of Seachem, 1 of H2Ocean and have just started a bucket of Reef Crystals in the can. In the past I used to use one can for only Instant Ocean and another for Seachem, the Instant Ocean can became very dirty while the Seachem stayed relatively clean.

Those of you who have never had this happen, do you use your newly mixed saltwater right away or do you let it sit for a few days? I let mine sit for a week before I use it.
