Calcium Isopod/Substrate Supplement

Calcium Substrate Supplement provides a natural source of calcium carbonate essential for the health of isopods, springtails, and plants. Its slow-release formula ensures a steady supply of calcium and trace minerals, promoting strong exoskeleton development for to it isopods and robust plant growth in your tank.  Great for bioactive tanks. For optimal results, apply 30ml per 4L of substrate initially, then reapply 5-10ml every 2 months or as needed to maintain nutrient balance. Alternatively apply light sprinkle to isopod food in bin once a week.  Note this is not a calcium vitamin dusting supplement for dart frogs or other reptile feeders as it is slow release and must breakdown over time.
