Review on CNZ Aquarium Flourescent Aquariums Landscaping by Brad Cao

looks good but at what price? I've bought them in the past and had no problems. As I increased my tank size, I simply bought more. When they arrived they were packaged differently and looked like there was a lot of trash mixed in, but I didn't think of that because I was going to rinse them anyway. Well, rinsing them as usual is clearly not enough. Within 4 days my rooster (which I had for about 2 years) died and the brand new guppies I added to the aquarium 2 days after installation died exactly 2 days after my rooster. When ALL the fish died, I realized it was clearly my fault. I went back to reviews of these stones and saw 6 reviews of fish dying from excess dirt shortly after use. So I emptied the tank and wiped the sides with a white paper towel. The paper towel was black afterwards! I threw rocks in the tub and filled it with water to rinse. When I drained it there was a black streak around my tub! I rinsed (not soaked - literally crouched next to the tub and rinsed those rocks) those damn rocks for over an hour, boiled them twice, and rinsed them again. I plan to buy more fish tomorrow and we'll see what happens. Conclusion - I will never buy aquarium stones from this company again and recommend you only buy from a more reputable company.
