Kent MarineTech M Magnesium Bottle 16 Fluid Ounces

Fast delivery. This is the only product that gets rid of biopsis! When I have a breakout I put this in the tank and it kills it

My hammer coral was not opening and I could not figure out why. I checked my magnesium and it was low. I used this to get it up to about 1300 ppm and the hammer coral is looking beautiful now. Make sure you test first. Too much can harm your invertebrates.

I've used a couple of different magnesium supplements for the reef tank. This one has been my favorite. Easy to use and accurate/consistent results.

Love this product

Bought with testing kit, test said I don't need to add any?? The two part I am using must have this in. It as I use a lot of two part and 100% lime water make up??

Kent is the brand I use for all the chems I dose; It is also what my LFS uses.PROS: Easy to use (no mixing like with the powdered stuff), was able to fix a major imbalance after only a week, you can use less than recommended to keep things in check for day-forward dosing.CONS: Tech M maxes out at 1350ppm for magnesium, which I know some reefers consider to be the minimum for their tank, but it is fine for my reef which is mostly LPS.If you have a larger tank (75G+), I would highly recommend getting a jug or multiple bottles of Tech M, as you will go through it rather quickly.

I do a daily healthy squirt in a 25 gal AIO, things are good.

I ordered a Salifert Mg test kit to verify my levels. As I had suspected, my Mg was low. I supplemented per the instructions and noticed my corals seemed happier the next day. I have also noticed that my coralline algae is now growing faster. I supplemented for a couple of days and my Mg levels have been normal since, which I think are now easier to maintain through normal water changes since the levels aren't too low. I suggest you go easy and test. Through my research Mg levels should be about 3X your Ca levels. Great product.
