I tested the Magnesium levels on some Oceanic salt that was mixing for about 12 hours. The Mg level was around 1040 at salinity of 1.026. The Alk was around 9 dkh and I didn't check Ca. Can someone please test their Oceanic salt and report the numbers? Iv'e always heard it should be around 1400 for oceanic. There is a possibility the Mag settles closer to the bottom and this was a newly opened bucket. Any feedback would be appreciated. ------------- Call or Text (801)834-3119 |

I've always had lower magnesium with Oceanic, so I supplement. Calcium is always pretty high for me. But it's all I've ever used, and don't plan on switching :) ------------- "Fishes live in the sea, as men do a-land; the great ones eat up the little ones." � William Shakespeare |

I don't use Oceanic, but use Red Sea, and it does the same. I get in the habit of rolling my bucket a few times before I make saltwater (could be an issue). The salt will stratify and heavier minerals will sink to the bottom. Or the salt could be a bad batch. Does Oceanic publish that the Mg should be higher at 1.026? I have read that some hobbiest get crazy and put their salt in those can shakers used to mix paints at Home Depot/Lowes. ------------- RedSea Max S400 - 90G Rimless Frag Tanks x2 - 185 Lookdown Bin |

Can't comment on Oceanic. But I use Reef crystals and always stir the salt when I first get it to make sure everything is even. Mixing to 1.026 I usually get Mag levels of around 1350-1380 ish and calc of 450/460. ------------- 150G mixed reef, growing coral farm.

Great idea, I will try rolling my bucket around and mixing it up and retesting again this weekend before a water change. If the levels don't change I might consider changing salt as I do not want to add Mg every time I do a water change. Magnesium Chloride can get expensive for a 100g system. ------------- Call or Text (801)834-3119 |

Mg settles to the bottom of the bucket so roll the bucket of dry salt mix?!  Isn't that just a silly rumor perpetuated by uninformed new hobbyists?The Mg is incorporated in salt crystals. It does not settle to the bottom simply because it is heavier than Cl, Ca, Na, etc.. If there was a need for stirring the dry mix to counteract setting in shipment, don't you think the manufacturers would say so on the label? It's more likely that there is a variability in Mg testing.

Mark, You can always be counted on to come in and say the opposite or attempt to be a ****. I assume you are retired and incredibly bored. You taunt people constantly and egg them on for more information or try to start debates. This hobby is built on people trying to help each other. I have read Randy Holmes discuss that mixing needs to happen and although I cannot personally verify that this is the case, he seems to be a highly qualified source. I don't understand how you state that you are here to help people, but when someone besides you give suggestions, you try and debate them. The suggestion was just a suggestion, read and passed down from other hobbyist. If its wrong, but something is working when they roll the bucks, who cares besides you? I think I have even heard you say that tanks/processes can be successful a million different ways. There are tons of massive systems that have little to no tech, and vice versa, that are successful.

RedSea, says to roll the buckets or mix bucket to bucket. But it is not in the directions for use. http://www.reefcentral.com/forums/showthread.php?t=2084966" rel="nofollow - http://www.reefcentral.com/forums/showthread.php?t=2084966 I must add that I don't dry mix my salt. Should I start? ------------- 210 G Filled 18 Mar 15 120 G Filled 11 Jun 16 |

I appreciate you posting this link. I will definitely add the salt to the water more slowly now as well as roll the bucket around on new salt buckets. I am hoping the levels of Mag will go up on this next test. ------------- Call or Text (801)834-3119 |
