Hi new to this thread. Like what I'm reading, particularly about not giving out advice w/o reliable test data. I'm sure this question has been asked/answered 100 times, but what's the best value test kit. I'm comfortable doing the titrations, and that's what I've done for years, but lately I've been lazy and just run down to the pool store to test. But I don't trust those guys either. Once I get my water tested, I'll be back to figure out my yellow algae problem. Many thanks
