Some deposit in D76-H

I made yesterday a new badge of D76-H and today I saw some little deposit on the bottom of the bottle. Is this normal?
I mixed very carefull and stirred every component until the stuff where dissolved. How can I avoid this. Thanks for helping me.
BTW the developer works as usual that's not the problem...

I see this just about every time I make up a batch of D76H, or anything else for that matter. It is not harmful; it will likely go into solution after a few days or weeks.

Not to worry.

Harry, I have this and have had this for decades. I just filter it with a coffee filter sitting in a funnel.

I suspect it is because I use normal tap water.

Never been a problem.

Mick.

I also use normal tap water. Next time I will try distilled water to see if there is any difference.
