SunGrow Snail and Crayfish Energy Balls, Enhance Color, Calcium-Rich Gray Pearls for Invertebrates, Functional and Beneficial Aquarium Decor, 10-Pieces per Pack

Drop and go! I put one each in my tanks with my triops, they will occasionally go nibble on them while skimming the floor is the tanks. So far so good, happy with my purchase

It works! I soaked in old tank water for 8 hours before putting in my 10 gallon, and tested the water.. raised the PH a lot but not the hardness, which I was looking for. Since putting them in the tank I haven't seen much difference, as the tank is bigger than the small cup I tested them in. Hopefully will raise PH and give my cherry shrimps some minerals to help their colors and molts. They sort of ignore them, similar to my other decor, just climbing on them. I do like that not much algae has grown on them since putting them in. I will update in the future if I see better results.

Looks like my aquarium (two small tanks) pets of cat fish (2), shrimp (14) and snails (~10) are enjoying the calcium ball. This was a real Prime Day value for the money. The size is perfect for my small tanks. Thank you.

I laughed out loud when I got this item in the mail. I definitely expected them to be bigger. My aquatic snail still loves them
