    Salifert calcium test

    Hello, I need a bit of help with the salifert calcium test. I can’t work out what the result is. I added in pretty much all of the Ca-2 until the water turned blue. I have attached a picture of how much I added and the blue water.

My apex has been saying it is usually at that measurement for the last month or so, ever since I set up the trident. But I just did a test with my Hannah tester and it...

    When to test Calcium & Alkalinity?

    At what point in the 4 month cycle of a new saltwater tank should I start testing & adjusting the Calcium & Alkalinity? Is it best to start immediate when you initially set up the tank? Or a few months down the road when a few fish are already living in the tank & I want to introduce coral?
