Seachem Laboratories Reef Advantage Magnesium Information


Product Manuals & Documentation

SeaChem Reef Advantage Magnesium ™ is a concentrated (80,000 ppm) optimized blend of magnesium, chloride, and sulfate salts designed to restore depleted levels of magnesium with minimal impact to the ionic ratios found in natural sea water. Reef Advantage Magnesium™ contains no ammonia! This is a common contaminant in every liquid magnesium supplement on the market. Severely depleted levels of magnesium (below 800 mg/L) can cause depressed pH levels and an inability to maintain proper calcium levels. Magnesium depletion is commonly associated with the use of kalkwasser. 300 g treats 5,000 L (1,300 gallons).

Does the job

Comments: A lot of reefers, especially when first starting out, don't realize the importance of magnesium. They hear calcium & alkalinity so much, they don't realize proper magnesium levels are crucial to help keeping your tank stable. If you are seriously deficient in magnesium, it is going to take a LOT of this supplement to raise your levels. I fill a bucket with R/O water, put a cup or so of the crystals in, drop a powerhead in to help dissolve the crystals for about 15-30 minutes, then add the mix to the tank. Seachem products have never let me down. Just remember, if you have a big tank and need to raise your levels up to 1300+, the biggest container (4L) is the best bang for your buck.

Measure before adjusting Mg

Comments: Be sure to order a magnesium test kit with the supplement. I bought the salifert kit and found it easy to interpret with highly reproducible results. You will use a lot of magnesium to get small bumps in the tank's magnesium level, but being in ionic balance has made my pH much easier to maintain. I needed to bring my magnesium level up ~300ppm, which took a lot of supplementation, but maintaining the new level has been easy since I switched to Seachem calcium supplement with maintenance levels of magnesium in it.

Comments: Got this about a week ago - has taken a few days of dosing to see any movement, but I'm hopeful that with small dosing increases my levels will reach their optimum. good bang for the buck on this product and of course the standard marinedepot.com speedy delivery and processing.
