Dosing Shirakura Liquid Mineral Ca in Singapore shrimp tanks
Singapore tap water comes through soft and low in minerals, and many keepers run RO on top of that for sensitive shrimp, which strips it further. This liquid calcium supplement is how a lot of our shrimp customers top those minerals back up between water changes. Calcium matters most around moulting, when a shrimp needs to rebuild its shell quickly, so a steady supply supports cleaner, less risky moults across a breeding colony.
Because it is a liquid, it lets you nudge mineral content in small, controlled steps rather than rebuilding GH from scratch, which suits an established tank you do not want to shock. We always pair dosing with a TDS pen so you can see what each addition actually does, and we keep changes gradual since abrupt swings stress Caridina far more than the slow drift of a soft-water tank.
