can this be used to check for ammonia in anti freeze?

This is designed to check for ammonia in air, so may not be accurate for other uses. There are other products available to check for ammonia in liquids. Although they usually only go to 8 - 10 ppm, there are water test strips in aquarium supplies that will check for ammonia.

do the test papers need to be dipped in a solution before testing the air ?

Not a solution. Just some distilled water.

Is this 15' or 50" ? Product description says 15' in one place and 50' in another. It also says 10/carton

The product is in a paper roll, 15 feet worth. You tear strips off the roll. to test.

Can you use this to test aquarium water?

No idea. I was using it to test air.
