This last batch of salt that I'm using is Reef Crystals and I'm down to the bottom of the bucket and my last two containers (32g plastic trash container) the make up water RO/DI mixed with Reef Crystals is dirty looking with film on the top? Is this normal for Reef Crystals? And should I discard it or use it? How long is make up water good for if kept at 79* and a good power head going in the container? Please help if you can. Thanks!
