Great product.
This works very well. My tank loves it. The coral is very happy and it didn’t have any side effects. Very easy to use and doesn’t cloud the water like others do. Great value.

Nice product that works as expected.
All I can say is "Brightwell Aquatics" makes some great products. I've used them for years. and trust my nano reef to them. Magnesium, Calcium, PH/Alk, pretty much anything I need to dose is from them.I have a 6 gallon nano reef tank and it can be a bit of a pain to dose, and keep parameters at the right levels.So far "Brightwell Aquatics" seems to work the best for smaller dosing without tanking or spiking.

Best magnesium we’ve used!
Love this magnesium! Works great for our reef tank and worth the price!! It’s not too powerful that it throws our water parameters off, but gives us a boost when needed! Have purchased multiple times and will purchase again in the future! Exactly what we needed!!

Good supplement to help reduce the need for water changes in small tanks
Easily added. Clear liquid did not cloud or Haze water. Did not have odor. I did notice immediate positive changes in corals. I did not notice any nitrate increases when adding this product. I used this in conjunction with another of their products to help reduce the amount of water changes I needed to do.

Keeping that mg over 1300 now
I’m very happy with this. The equation in the directions gives exactly the result it says it will. While the directions say dose twice a week without doing the math, I did the math and tracked how much I needed per week and I now dose daily 10mL as that is what my tank uses every day and I want consistency. For the first three years, I never dosed when I just had my Duncan and palytoa, and they were plenty happy with very occasional water changes. But I wanted to get new coral - so I’m learning a lot. Must keep magnesium up.

Excellent!
While buying powder or granulate to dilute in water is cheaper. This solution is more concentrated that the one you can make with the powder so you achieve your goal faster.
