What is the dosage and what are your experiences with these rocks? Is there a possibility of overdosing? Do these rocks alter the GH of the water? What are some good brands? :red_mouth

Ebiken Kou-yang white mineral stone is a calcium bentonite based mineral rock that has a very high composition of calcium which invertebrates use to help with molting and aid in thicker and shinier whites. It also acts as an area for inverts to pick on for supplement minerals.
Use: It is recommended that 10 grams be used for every 10-20 gallons of water. For the best results, use a tooth brush to brush off the algae that grows on the surface of the mineral rock once awhile for the best performance.
