AquaChek Phosphate Test Kit

Nice kit, but only reads up to 1000 ppb

Pretty cheap way to test for phosphates. This kit will show if phosphates are approximately 200 or 500 or 1000 ppb. But, if phosphates are over 1000, you'll have to test and add a phosphate remover more than one time.

Good product. Best price shipped to home
