ABYSS Genuine Japanese Deep Sea Mineral Stone 250 grams

Our maifan and tourmaline mineral balls are considered essential for keeping Neocaridina and Caridina shrimp in parts of Asia. The small mineral balls release beneficial components into the aquarium such as calcium and magnesium which are needed to keep shrimp in optimum condition. 

Maifan has negatively charged ions like montmorillonite which can absorb contaminants and heavy metals keeping the aquarium crystal clear. Tourmaline mineral balls are remarkable at boosting nitrifying bacteria growth as well as providing aquariums plants with essential trace elements for prolific growth.

NOTE: You may see maifan and tourmaline mineral balls sold on large online marketplaces as Calcium-Rich Mineral Beads for Betta. These beads increase the GH and KH of the aquarium water which is not ideal for Bettas and can affect their health negatively. 

If you need a calcium boost for your Betta then try our Caridina Vital Authentic Kishu Binchotan Carbon Wood. It will provide calcium as well as other health-boosting elements without heavily boosting the GH and KH of the aquarium.
