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. Magnesium also helps to maintain the correct combination of calcium concentration and alkalinity as it slows down the formation of calcium

Works great, could use a better sprayer
Style: Kids SPF 50, Size: 5 Fl Oz (Pack of 1)
I gave it 4 stars ONLY because I've had the nozzle break on at least 1 of these. So they could improve the way it sprays, but overall I'm very happy with the product. It keeps my whole family from getting burned and goes on clear. I love this because my kids always complain that they don't like the whitecast, so this one is a keeper!

Really nice sunscreen
Style: Kids SPF 50, Size: 5 Fl Oz (Pack of 1)
I always buy kids sunscreen because everything else burns my eyes. I haven't notices this stuff burning. It smells really nice and doesn't feel yucky going on like some stuff does.

DOESNT SPRAY do not buy
Style: Kids SPF 50, Size: 5 Fl Oz (Pack of 1)
Doesn’t work AT ALL. And I’m annoyed because it’s not eligible for return even with prime. What am I supposed to do with a sunscreen that won’t spray? YES, it’s in thru blocked position, it will not spray. I’d love my money back please.
