Review on 🐠 ZHUDDONG Aquarium Gravel - Polished Natural Decorative Fish Tank Gravel, Mixed Color Stones, for Aquariums, Landscaping, Vase Fillers - 3LB (Jade) by Angela Jackson

Revainrating 2 out of 5

Be careful with fish

Although these stones are great, after soaking overnight and testing the pH of the water it was significantly higher than my tap water. (The purple color is related to the water the stones were soaked in - 8.4. The tap water was 7.4.) That's a big enough pH jump that I thought it wasn't safe for my fish. I would be wary if you're thinking of using this gravel in an aquarium.

Pros
  • Positive only
Cons
  • Sufficient
