I do that but it seams to turn blue around 1.2 ive tried it twice and i mead from where the bottom of the black part is and maybe flakes with mire phosphates? Im using tdo chroma boost pellets
Yup, you can try some flakes as well.
How many times a day do you feed?
Not sure why it would be turning blue immediately. I can’t imagine your calcium is that low. No corals right?
So for salifert you add 2 ml water to the vial. Then 1 level scoop of powder (don’t swirl vial). Then fill syringe with 1 ml liquid and dispense to the .4 ml line. Now swirl and it should turn pink. Then add drop by drop and swirl until it’s blue.
If you do this and it’s not working the test kit may be bad. It should have an expiration date on it as well.
