Eric's 400g Marineland Reef Tank Build

I have a Hanna checker and Red Sea that always line up. I'm going to run the Red Sea tests for all 3 again tonight.

So there might be something wrong with the Hanna checker for calcium. It gave me 360 while the Red Sea gave me 480! Maybe I am just doing it wrong. The Alk was the same with both @ 9.0 and magnesium was 1400 with the Red Sea test. I will take a water sample to a lfs tomorrow and figure out which one is right.

Turns out the Hanna checker was wrong. I work near them and will drop by to discuss it with them when I get back in town. Been WAY too busy lately! Thanks for checking in Chris.

Idk, have not had a chance to look into yet. Since I have the other test kit, I just use it for Ca.
