![]() Ok
I am about to give up with this reef crystal. I bought another reef crystal IO bucket and mix the salt with RO/DI water and leave it for a day. I also dosed 8 tsp of Seachem Advance Magnesium (which should increase 55 ppm) to the water before adding the salt. Well. I test the MG with two different test kits and they all come to be around 1200 What am i missing? If you buy IO salt and bulk Mg from chemmaster, how many tsp do you add to 15 gallon new water? Thanks. |

![]() A cup full should get you to where you want to be.
I make about 27gal at a time to do a 10% water change on my system. I use half IO salt and half Seachem Reef salt then add a little more than 2 cups of a similar Mg mix. By doing so my tanks Ca is 450, Alk is 9dkh and Mg is 1450. Or use this calculator http://home.comcast.net/~jdieck1/chemcalc.html To raise 15gal of water from Mg 1000 to 1500 use 8.3oz (56.3 tsp aka 1 cup). If you dont want to go as high as 1500 try 3/4 cup.

If mixed to a s.g. of 1.0264 (35ppt) then you should be finding that the new IO should be about 400 ppm and 1350 ppm magnesium or so. If your s.g. is lower then your mag level will also be lower, but with the new salt, your s.g. would probably have to be around 1.023 to get mag levels of 1200. To boost magnesium takes a lot more of whatever product you are using to boost it, than most people would expect, because the flake is mostly water. (hexahydrate) |

![]() I use 3 tsp of Ca and 1 cup of Mg for 15g of IO salt at 1.024 Sg isn't 1.026 a little high ?

When I started seventeen years ago, it was normal to keep 1.026 for a reef tank as that is what the majority of the ocean water is at, where our fish and corals come from. Many hobbyists keeping fish only used water with less salt content for one reason or another, but the same hobbyists kept the s.g. at 1.026 for their reef tank because it was better for the inverts and corals. Based on my years of reading the forums on RC, I believe that the majority of hobbyists are using at least 1.025 - 1.026. |

![]() Just be sure to make the change gradual.
Perhaps just add water mixed at 1.028 instead of your normal top up water (to replace evaporation) until the level comes up to where you choose to keep it. That being said, there are many who keep their reef tanks at 1.024. Obviously you do need to boost the calcium and magnesium if you want NSW levels for those elements, but not wanting the NSW s.g. level. With FOWLR, changes to salinity still need to make made gradually in an upwards direction, but can be made rapidly in the downward direction because of the way osmoregulation works with fish. |

![]() I keep my reef tank @1.026 now using IO reef crystals and have notice that my coral's & livstock seem to like it better. My FOWLR is @1.024 using just the IO salt.
