Got back into the hobby about 8 months ago. Having some issues with cyno and decided to pull out my phosphate checker. The reagents are very expired (2015) Do they go bad? If they do go bad will the just be off by a larger margin or will the test fail?
If the reagents are useless what phosphate test is recommended? HI736 ?
Have the hanna meters gotten better than turning off every 2:30 seconds where you have to rush thru a test?
