  • Easy to do By on 8/16/2017

    Mixing this is easy to do. It saves money since I'm not paying to ship RO water.
  • Mag sulfate By on 7/16/2017

    Very easily mixed with power head in 5 gallon bucket all around great product specially if you are experiencing low mag levels.
  • Good stuff By on 10/11/2016

    Works great, as expected. Priced right, mixes clear, and the BRS calculator is spot on. Can't really ask for more then that.
  • Good Stuff! By on 4/13/2016

    Although the product needs to be shaken quite a bit and takes a couple of days to dissolve, the corals have all responded well. It also mixes crystal clear.
  • Great solution for magnesium dosing By on 2/8/2016

    Easy to use - mix in a jug, use the calculator, dose it in the tank. Just works!
  • Good product. By on 12/18/2015

  • Safe your self money and buy this in bulk over premix liquid Mg By on 11/26/2015

    Work better and safes money over buying the premixed liquid magnesium like kent.
  • The good stuff By on 9/15/2015

    Do not be tempted to buy a lower grade product from other sources. This is a pharmacy grade product that mixes clear. Some cheaper stuff is available but it us designed as fertilizer and is not worth the risk.
  • Like it! By on 6/10/2015

    Great product, easy to use and mix. NEED TO KEEP IT IN DRY PLACE! It picks up moisture very easily, even in the container and then it's tough to break apart.
  • Excellent product By on 6/7/2015

    I just started using this in combination with the magnesium chloride...what a difference! My maginesium levels have been stable now for weeks. Seriously impressed!
