value By Traci on 4/7/2013Traci would recommend this product to a friendhave tried other mag additives, this gives the best results with minimal amounts
Very good product, cost effect By matthew on 1/12/2013matthew would recommend this product to a friendI've been using this product for a couple years with good results. Instructions are easy and the BRS reef calculator makes dosing this product so easy. Using the BRS calculator and Bubble Magus doser with this product is basically a "set it and forget it" type of deal, and I test magnesium a couple times per week to double check this. This product is so much cheaper than other bottled liquid magnesium products if you don't mind mixing the solution up yourself (which is very easy).
Good Product By David on 11/27/2012David would recommend this product to a friendBest price I found online, Thanks BRS.
I started dosing my tank and it had 1100ppm Magnesium.
Now it's up I got it up to 1400 ppm now.
Just make sure to order both mix solutions.

can a person use this in the bathtub instead of magnesium chloride flakes?
Bulk Reef Supply Sorry, but these products are aquarium supplements and are in no way for human consumption or use.

What is the difference between Mag Sulfate and Chloride? Do i need to add both to tank? I use a two part Alk/Cal system now with the mechanical dosing system. I was thinking of adding an additional dosing pump for the Mag solution. RECOMMENDATIONS??
Bulk Reef Supply Hey John,
Most folks use a combination of magnesium chloride and magnesium sulfate when adding the magnesium to the aquarium. With a two part system its generally a ratio of 5 cups of magnesium chloride to 3 cups of magnesium sulfate in 1g of water. This is to help keep the ratio of chloride and sulfate ions as close to what they are in natural seawater as possible.
There certainly is no reason you can't use a dosing pump for your magnesium. Most folks just do it by hand though as it usually only needs to be dosed once a week or commonly as little as once a month.
