E.S.V. B-Ionic Seawater System Salt Mix - Makes 50 Gallons of Saltwater
A unique solution to many of the problems associated with all dry synthetic seawater blends.
Problem: All dry blends may not be homogenous resulting in considerable chemical variations not only from batch to batch but also from within the same container. Aggravating this further, humidity contamination during storage can result in localized precipitation reactions.
Solution: B-Ionic® Seawater System avoids these problems by providing the two dominant salts in our formulation in separate containers. All other major, minor, and trace elements are pre-dissolved in a highly concentrated two component liquid system. These dry and liquid components can easily be measured for any size batch of synthetic seawater.
Problem: It is now recognized that most reagent grade salts can contain contaminants (trace metals, etc.) at levels which may inhibit the growth of some algae species from low nutrient environments (oligotrophic) such as coral reefs.
Solution: B-Ionic® Seawater System addresses this issue by providing ultra-low heavy metal Sodium Chloride (max. allowable less than half max. allowable for reagent grade sodium chloride) and USP grade Magnesium Sulfate as the dry components of the system. In addition, all other chemicals pre-dissolved in our liquid components are subject to our three phase purification process resulting in significant lowering of contaminants, including phosphate.
Problem: Many all dry blends take excessive time to completely dissolve. Addition of newly mixed batches to the aquarium can cause irritation to inhabitants upon exposure to non-dissolved salt micro-particles.
Solution: B-Ionic® Seawater System avoids this problem by providing all of the slower dissolving ingredients in a pre-dissolved solution form. Batches can be used within 10 minutes of preparation with no adverse effects providing initial RO and/or DI water contains sufficient dissolved oxygen.

What is the MG and CA on a freshly mix? Thanks!

By : Frederick Perez, San Diego
This is the only salt I will use or recommend. Measuring components is no harder than any other reefing task and the precise predictable results are mandatory for any reef in my care! Save money on other areas of the hobby, this is worth every penny.
CONS
Slightly expensive, slightly more work to mix

ESV is hands down the best salt mix. It's extremely consistent and well worth the little bit of extra effort it requires. I highly recommend getting a cheap digital kitchen scale to measure out the components.
This is also a great salt to use if you're an SPS keeper and carbon dosing. It mixes at a lower Kh than a lot of other salts.Hide
ESV is simply the best stuff. From their 2 part, to their salt mix.

ESV is simply the best stuff. From their 2 part, to their salt mix.
I have to say, I was a little hesitant on the idea of mixing up your own batch, not because of the complexity, but more so the time involved. In fact, it could not be any easier! It also mixes incredible fast therefore salt is ready much faster than any other brand I have used. It is more than competitively priced, and the water is crystal clear and consistent each time. I just wish they made larger mix kits.Hide
I love ESV B-Ionic salt mix and have been using it for years.
It mixes quickly, is ready to use almost immediately and leaves no residue behind.
I'm not a fan of the new barrel packaging. If the tab rips off for you the way it did for me, go grab a knife or a razor. I tried to lever the top off ...Read More

I'm not a fan of the new barrel packaging. If the tab rips off for you the way it did for me, go grab a knife or a razor. I tried to lever the top off without cutting the remains of the edge,and just about killed myself. Lesson learned.Hide
I've only ever used ESV salt. It mixes clear and leaves very little residue. My corals don't mind when I do water changes, because every batch I make matches my water in my reef. DKH of around 9.0 is great to see in a reef salt. I recommend this salt to anyone wanting a consistent issue free salt.
