Just after some advice re: Magnesium. I tested my magnesium today using salifert kit for the first time and mag was 1170ppm, Kh = 7, Ca - 400ppm, salinity 1.025, phosphate - zero (reads as this but i know its probably higher).
anyway so i should probably look at raising the magnesium to around 1250ppm? So i'm not too familar about how to raise mag, but from what i've read i should look at getting some mag flake. How do you dose this in to the aquarium and where can i get smaller quantities of mag. I've read you can buy 25kg bags but this would probably take a long time to get through.
