I just used the red sea foundation magnesium test kit and used all of the titration solution and it didn't turn blue. What does this mean? it's a evo 13.5. 1 year old. I have tons of corals in it (27) none of the coral seem affected( yet) do I need to start dosing? Both my calcium and alk are down from their normal range.
