I have an external Iwaki doing most of the mixing and also have a Koralia 2 inside the bucket pointed towards the surface. I dump 13 cups, a cup at a time as the water is being pumped into the Brute. It is usually cloudy for at least 24 hours if not longer but is pretty clear after 48 hours. I get a white residue coating the inside of the container that will wipe off as long as I don't let it dry for too long. If it drys and I do it again it becomes hardened, turns brown and only comes off with a vinegar soaking and scrubbing. I also get some small brownish pellets laying at the bottom of the container.
I will accept that I'm putting the salt in too quickly as a partial explanation, however I've started putting the two day old mixed water into another brute that is on wheels to take it to my frag system and it will still end up with the white residue. Does some of the calcium precipitate stay suspended in the water even after it has been mixing for several days?
