  • Really good salt By luis on 2/15/2015

    Like others have said no residue in the mixing tank I used to hate that brown nasty residue that was left by other salt mixes. I would never go back to another salt mix this is my permanent salt to stick too. Also, levels are great and consistent. I bought three from last 2014 Black Friday so trust me I have seen good very good result from this salt mix and you will to!!!
  • Amazing salt mix By kyle on 2/11/2015

    this salt mix is great. like others have stated i have no weird residue left in the container i used for water changes. it dissolves quickly and easily. it comes in a very heavy duty plastic bag inside the box. i have only used red sea pro mix and this one and i bought 3 of these when they were on sale!
  • Love this Salt! By Jon Norris Marine on 2/2/2015

    I use this salt on all my tanks, service calls and saw a huge difference in clarity and quality of marine life. Mixes easy and clears up really quick!
  • Values for our both hw-Marinemix & hw-Marinemix Reefer By Robert on 1/21/2015

    SALT: Please consider that all given values are average values of multiple testing.
    Variant factors, so as extremely changed salinity/density, of the prepared marine will make the values not predictable.

    Approximated values can only be obtained through carried out multiple testing and analyzing methods under laboratory conditions.

    We estimate that the given value of 1.0264 is a density (as you give a temperature of 25°C/77°f) and not a gravimetric based value.

    If you mix at this density you will reach a very high salinity of 39 psu, which represent the upper limit value of natural marine environment (only possible to find under special circumstances in some cost region of the red sea).

    The values for our both hw-Marinemix, at a Salinity of 34 psu (equal to a density of 1022.6 at 25°C(77°f) are as following:

    hw-Marinemix professional:
    Ca: 400 – 430 mg/l
    Mg: 1230 – 1260 mg/l
    dKH°: 8,2 – 8,5
    Alkalinity (acid capacity): 2,93 – 3,04 (dKH° divided through 2.8)

    hw-Marinemix reefer:
    Ca: 420 – 440 mg/l
    Mg: 1310 – 1330 mg/l
    dKH°: 8,4 – 8,7
    Alkalinity (acid capacity): 3,00– 3,11 (dKH° divided through 2.8)
  • Mixes Clean, Fast and has great levels... By Will on 1/19/2015

    Have used RC, Kent, Red Sea Coral Pro and a few others. Not going back to any of them... I mixed this to 1.026 sg @ 77.5 and had the following results. These are based on the average of several tests which were all close ( Hanna and Salifert for CA and ALK, Red Sea and Salifert for MG test)
    CA - 450, ALK 8.96, MG- 1440. Fastest and cleanest mixing salt and no residue at all. May cost a bit more but worth it IMO. Coral all looks great and I already run my MG above 1400 so this is perfect.
  • Good Stuff By Schmoopie on 1/11/2015

    Just changed over and everything seems happy. Need to check the Mag level and some others but it looks good so far
  • Great product By Michael on 1/7/2015

    I purchased this salt having heard about other salts leaving behind residue and/or being more difficult to dissolve. I must say this was very quick to dissolve and hasn't left any residue behind yet. Costs more, but seems to be worth it!
  • CLEAN AND CLEAR!!!! By Tyson on 1/4/2015

    Mixes EXTREMELY easily, has the consistency of table sugar. Clear within 20 minutes. No more clouded tank after water change which was a problem with Red Sea Coral Pro. Bottom of my mixing container is spotless after using this.

    I switched from RSCP and will stick with the Reefer!
  • Cycling a new tank By Jeff on 12/31/2014

    Minimal amounts of algae and diatoms when I started up a tank with this salt. I was amazed compared to IO and red sea. Mixes clean just like red sea but it clears up quicker. Time will tell how tis works out but it looks good.
  • great salt mix By jersey pete on 12/29/2014

    I mixed this up and wow. Dissolved almost instantly. Changed water next day. One day later my corals were looking the best ive seen. The only down side is i bought a couple boxes on sale for 49.00. Now im going to have to pay 75. Well we all know this hobby aint cheap.
  • good salt By class on 12/29/2014

    Need to be able to buy with out spending 175 to get free shipping if not will cost like 40 to ship one box
  • Love this salt mix! By Nick on 12/27/2014

    I gotta say I love this salt! I've used almost all other commercially available salts in the past and this one beats them all. For starters, it mixes clean, no residue at the bottom of my container, it mixes fast and clears up fast as well. My corals and fish seem "happier"? Cant really describe it but the coral polyps are reaching higher than on Salinity salt, IO or Red Sea. This salt has become a staple, yes it costs more, but isn't the fact that your expensive livestock is better off reason enough for spending more? It is for me. I do not dose, so the fact that the calcium, Mg, alk and all other minerals are always in line and stable from box to box alone is worth the price jump. Only use with RODI water, if you don't, this salt is wasted.
