Magnesion Liquid Salt Water Conditioner - Concentrated Magnesium Supplement For Reef and Marine Aquariums, 67.6 fl oz

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.

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.

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.

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!!

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.

Price was right

I've been adding 30ML of this magnesium to my 125 Gallon reef tank. Tank readings have gone from 1200ppm to 1260ppm. I'm adding it slowly. Only 3 days a week. It's going to take a while but I'm working on getting up to 1450ppm.

I just add 20ml when my Mag is under 1300 and bring my Mag to 14XX in my 75g mix reef tank.
