I have never added Mg to my tank and this is the only brand of salt I have ever used. My Magnesium is at 1700. I check it regularly and do a 10% wc weekly. Is this a defect in the salt? My specific gravity is consistently kept at 1.025. The side of the box says at 1.026 it should be 1345. I can't help but think this is why I keep losing snails and crabs. What can be done to lower Magnesium?
Question by: Maggie on Nov 22, 2017, 1:30 PM
There are claims that Reef Crystals can be high in magnesium and by switching to a salt like Red Sea or how you will see more consistent elemental levels. Lower magnesium will just take time. You can do a couple of water changes that has more moderate magnesium levels, but it may take a few to get the levels down under 1400. I would suggest looking into the blue buckets of Red Sea Salt.

What do you reccomend I use to mix the salt? I'm thinking of using a brute 55 gal trashcan for mixing in. Also how many watts for a heater to heat the newly mixed saltwater. Thanks.

Hey, great question! Generally any untreated plastic container is fairly safe to mix saltwater in, but many plastics will leach some amount of phosphate into the water over time from the plasticizers. #2 HDPE and #5 Polypropylene without added chemicals are usually considered the safest and best for reef purposes. The Brute trash cans should be totally fine to use and are a popular solution in the reefing community. Have a great day!
