White slime in water change water

[BryanF]

Did a water change today and this what is lining my bin of new water. Thick and slimy. I use rodi water and Kent salt. I have never seen this before. Any ideas what it is? Should I have used the water?

Precipitate from mixing

Good, bad, or indifferent? Thanks for the advice..

It was mixing for much longer than usual. Probably the better part of two weeks.

What you're seeing is the trace elements from mixing of the salt. Calc alk etc. so values might be a little lower. "Shouldn't" be a problem

Test the water. This happens when the major elements are not in/near NSW proportion or quantity. Non NSW parameter salt is one reason, but if you put in all of the salt with not-enough water (even if you are going to add it later), it can precipitate. You can also get this from batches that are off-the-norm from the manufacturer.

To avoid this, use a reef-quality salt, add salt to the full volume of COLD water and heat after mixed.
