Mixing reservoir water dirty

[Koleswrath]

Hey thanks for bringing this up. I noticed the same thing when I started using Reef Crystals. Funny thing is that it started about 1/4 way through the bucket. You'd think they'd mention this on the packaging. I've been scrubbing my powerhead and mixing containers thinking they had bacterial buildup on them or something.
Haven't noticed any ill effects from it so far.
