  • Excellent By on 5/11/2017

    Have used this for the past several years ....excellent product and the tank shows it
  • Great Product! By on 4/24/2017

    As soon as I started using ESV 2-part the coralline algae bloomed and is now taking over my back glass and rock.
  • High Quality Product Keeps Levels Balanced By on 4/9/2017

    My CA and ALK remain stable and my inhabitants healthy. I dose each part 4 times per day at separate intervals. You do not want to run each part at the same time. The fluids also drip into a high flow area of the sump. I recommend trying this product out.
  • Should be called ICONIC By on 11/20/2016

    Hands down best 2 part on market. If you need a perfect healthyreef this is the stuff been using for many many years.
  • Great 2-part dosing solution By on 7/29/2016

    This is the best 2-part dosing solution available. And it's so much easier than the powders.
    Highly recommend
  • Great stuff By on 6/13/2016

    Never used any other product. Alk and calc levels have always been great. If it ain't broke, don't fix it.
  • ESV dosing By on 6/9/2016

    Seems to work well and says it also replenishes many of the trace elements that sea water contains. It's been working for me for a couple years now.
  • Awesome product By on 5/6/2016

    I use the two-part system via dosing pumps for about 6 years now. Easy to use and consistently keeps my CA, MG and, along with the Alkalinity (part 1), keeps that in check too.
  • easy By on 3/18/2016

    I only have a 20 gallon so dosing can be a little bit a of pain. But this seems to work great my corals look pretty good..
  • Easy, mixes clean, and works By on 2/24/2016

    I set up a 2 part doser a few months back and have so far only used ESV's 2 part so I don't have much to compare it to. However, I find this stuff is easier than mixing up powders/salts (still do that with my Mg) even if I have to wait a day or two for it to dissolve completely. Once it's mixed I have never seen it separate/precipitate out again and it stays nice and clear.
