Are this perimeter OK?

That’s what I have heard as well. But don’t know anyone that is using it. Do you know anything about the Hanna all in one kit?

I have the hanna marine master, its fine except for the calcium test, which only uses .1ml of tank water to try and determine calcium. Very strange.

Is your alk actually moving that much in a day, and phosphates 1.5 to 0.2 in a day?

That will kill corals very quickly.

I did have 1 die.

Is it accurate though? Does it take a while for testing?

Phosphate 3min, nitrate 7min. Alk instant. Mag takes 7min I think, but I don't test that anymore, and it is known to be plenty accurate.

Its just a bummer the calcium test is not great. I'm getting a salifert or redsea today.

If you are looking to test calcium (I do not), then Salifert is a fine way to go.
