All these 3 part calcium test are just not quick enough I have 7 tanks In my house alone and maintain a few for friends and fam and it takes me forever to test I need a one step easy means of testing my calcium a test strip anything

sure......just take a sample from each tank to your local water supplier. they can test it a lot more accuratly, of course.......its going to cost you. your local pool supplier mght do it for you as well. But each test is still going to take 4-5 minutes....
