Review on Kent Marine Magnesium 16 Ounce Bottle by Holly Rodriguez

Kent is the brand name I use for all the chemicals I distribute; This is also what my LFS uses. PROS: Easy to use (doesn't mix like powder), was able to correct serious imbalances in just a week, you can use less than recommended to keep things in check for the day ahead. CONS: Tech M has a maximum magnesium content of 1350 Parts per million, which some reefers consider minimal for their tank, but that's fine for my reef, which is mostly LPS. If you have a larger tank (75G+) I highly recommend getting a tankard or several bottles of Tech M as you will use it up fairly quickly.
