Let me tell you about my love-hate relationship with these little white rocks. At first glance, they look like aquarium decor straight out of a Pinterest board - rustic, natural, and perfect for creating those Instagram-worthy shrimp tank scenes.

The GOOD: My cherry shrimp went absolutely nuts for these! Within hours of adding them, I spotted my blue dreams doing their happy dance across the surface. The calcium boost seems legit - I've noticed brighter colors and smoother molts. They're like a buffet and playground combined for crustaceans.

The CAUTION: That "water conditioner" claim? Take it with a grain of salt (pun intended). In my 10-gallon tank, they dissolved faster than expected. Pro tip: Start with just 1-2 rocks unless you want to play water parameter whack-a-mole.

REAL TALK on the dust: Oh boy, rinse these bad boys like your shrimp's lives depend on it (because they kinda do). The first time I added them without proper rinsing, my tank looked like I'd poured in milk. Not cute.

Size surprise: Don't expect boulders - these are more like large gravel pieces. Perfect for nano tanks but might get lost in bigger setups. Mine have lasted about 6 weeks so far with moderate dissolving.

Final verdict? Great supplemental calcium source and enrichment tool, but pair them with a proper water conditioner. Your shrimp will thank you with vibrant colors and happy molts!
