Salifert Magnesium Test KitLose your instructions? They can be found under the documents tab! Magnesium is present in natural sea water in a fairly high concentration (1350 1500 mg L) and is an essential element of chlorophyll which is necessary for photosynthesis. Without photosynthesis plants, algae and coral would not be able to survive.

Nicely made looks attractive.
Color: Beige
This is a nicely made attractive tray. I use it on my coffee table in the living room. The color is very nice and sort of a soft creamy rose shade.

Great for holding/hiding clutter
Color: Green
Nice. Just what I needed to keep things from rolling around on my side table. The sides are high enough to somewhat hide them, so it looks much neater. Well made and I like the moss green color,

Cute for office organizing
Color: White
This is such a cute organizer tray. I got it for my home office. It matched a different set I purchased, but completes my home office look. It's a small tray, but the space I need it for is small so it worked perfectly. It's a catch all for some of my work stuff, but it keeps the area looking clean and organized.
