- •
CaCO3 seed ASP of Ca is sensitive to phosphate, magnesium and carbonate levels.
- •
CaHPO4 seed ASP of Ca was unaffected by phosphate, magnesium and carbonate.
- •
CaCO3 seed ASP of Ca is suited to water with low Mg2+, CO32−, and PO43.
- •
CaHPO4 seed ASP of Ca is suited to water with high Mg2+ and CO32− such as CSG water.
