Quick Overview

Why does BRS recommend this?

We have been using HW salt in our office tanks for a while with great success.  The salt is very consistent and mixes quickly and clean.  With no unnecessary added chemicals that most salt mixes add to appear clean, HW has passed the test, and standards that many public aquariums and high end displays require in a salt mix.

hw-Marinemix Reefer Salt Mix is a high purity blend of salt mix produced using a synthetic process and does not contain any recycled components. Created specifically for the reef aquarium and the constant demand for minerals, trace elements, amino acids and biocatalysts. Provides enhanced calcium and magnesium concentrations for vigorous growth of corals.

  • One of the first synthetic salt mixes ever produced

  • No anti-caking agents

  • No chemical or environmental pollutants, no nitrates, phosphates or silicates

  • Natural, stable pH and optimal alkalinity

  • Contains no EDTA which can chelate many necessary trace elements

  • Optimized with amino acids and organically stabilized iodine - great for the reef hobbyist

  • Makes approx. 160 Gallons of solution at 1.024 salinity

  • Best Salt By Lukas on 2/1/2016

    I've noted nothing but good things with this salt (cost aside). My corals have all perked up. Especially when combined with dosing biotip and nanotip. Mixes clear and quickly.

    On a side note coming from using Red Sea's Coral Pro Salt to this, there's a little difference in the mixing. With little available from the manufacturer in terms of mixing instructions I did have to toss a batch of saltwater. Redsea they state to mix on the colder side to avoid precipitation. I found this salt to have the opposite issue. When mixed cold I had significant precipitation when I warmed it up. But when mixed into 78 degree water I have no preciptates at all.
  • Much better than reef crystals By Mark on 1/20/2016

    I was using reef crystals for almost a year when I set up my first tank. Once I got a better handle on keeping the big three parameters where I wanted them I found I was having to dose a ton of calcium and magnesium to my make up water. With this I don't have to add anything. The second box I just received tested at higher calcium and magnesium than the first box. The last batch I mixed tested: Ca - 450, Alk - 9.5, Mag - 1400
  • best salt out there By james on 1/1/2016

    there is not a salt that mixes as fast or leaves zero residue when mixed in container for water changes.
  • Worth The Extra $$$ By Jeffrey on 12/31/2015

    I started using IO salt and had less than good results so I switched to Red Sea Coral Pro which was tons better but so high in the elements, it affected my dosing which I didn't like, so I switched to this salt and won't use anything else now. I still use Red Sea for my nano's because I find it keeps the parameters in line without having to dose daily, but this salt is the only one that goes into my 57 gallon reef now.
  • Only Salt I will Ever Use!! By Tricia on 12/26/2015

    I have had several LFS's test my water and tell me I am within their top 1% tested for "perfect parameters" etc. They all want to know what salt it is and where I got it. Thing is, I only have a IM 16 gallon all in one Nano tank and I can run with "The Big Boys"! That says a lot. I love this salt. The LFS wants to know how I keep these perfect "benchmarks" every time I let them test (I usually do my own, but some times a second opinion is a good thing!). I am actually getting worried because BRS has been "Out of Stock" for awhile and I am running low. Don't want to go with the other stuff!
  • Only Salt I Use By GLC on 12/16/2015

    Switched to HW-Reefer salt about a year ago and my reef has never been happier. Mixes clean and clear and corals have exploded with growth! Love this salt........
  • Excellent product By Kim on 12/12/2015

    I mix 4 gallons for a daily water change on my system. I love how quickly this product mixes and never leaves clumps or residue behind. I can mix and heat 4 gallon in 5-10 minutes. Can't ask for better results than that. Love it, love it, love it. Thank you BRS for stocking it.
  • The best of the best By Mack Jr on 12/11/2015

    I been using Red Sea pro for over a year until my reef club president introduced me into this salt! No more grime on in my brute container! Higher levels ! Corals are happy and flourishing !
  • Great Product By Das R on 12/11/2015

    This salt mixes extremely fast and clear. No residues, films, or anything. My results:
    ALK - 7.7
    CAL - 330
    MAG - 1200

    ALK - 9.1
    CAL - 425
    MAG - 1400
  • Only salt I will use now By Alex on 12/10/2015

    Hands down I love this salt and so do my corals. I have had 0 issues with this salt. I mix it as I need it (ready in an hour) and leave 0 residue. It mixes clear in about 5-10 min . I did notice that to get 1.025 you need about 2 3/4 cups (a little more then red sea if I remember correctly) Came here to buy another box as im low but currently sold out. Hopefully they get more in soon. 10 10 will buy again.

    Looks Good.
  • Must be the Texas weather or something else. By Brandon on 12/6/2015

    This review is not on parameters or quality. When I very first opened the box I thought that the bag was air sealed tight, due to the fact the salt was in one massive chunk. After further inspection after opening the bag realizing it was in fact in one massive chunk had to close the bag best as I could and basically slam the bag on the floor several times , like you would a bag of ice. It was still in chunks then I transferred it over to my moisture sealed five gallon bucket and took me over an hour to break those pieces up. I thought this was normal due to no caking agents in the mix, but after reading how fine this salt is and others salt not being chunked together like mine was . I was disappointed. Now on to mixing , I mix up 15 gallons for every water change and so far it takes just a tad over 9 cups to mix to 1.026 , which is more cups then I have ever had to use with any other salt mix out there even cheaper salt mixes. At this rate this salt wont even last me two months , when others have lasted me around 4 months. I wondered if this was due to the fact that I am not able to get the entire salt mixed before my water change due to all of the chucks. I will be giving this salt another chance when I need more if it is in stock ,if not I will go back to the salt I was using. Just because I do not gauge successful reef keeping on salt mix, but on consistency.
