Can I put river rocks in my aquarium?
Consequently, can I use river stones in my aquarium?
You should be careful taking things from the wild and putting them in your aquarium. They can carry diseases and parasites. The bleach will probably take care of that, but you may want to soak the rocks in clean water for a few days, then let them dry in the sun. I have river rocks myself and are a great decoration.
Similarly, you may ask, can I put rocks from outside in my aquarium?
The principal danger of using your own outdoor gravel and stones in an aquarium is the possibility that they contain calcium, which can alter the pH of aquarium water. If there is a significant increase, these rocks or gravel will cause problems in your aquarium.
After the rock has been boiled for about 20-30 minutes, it can be removed from the pot. It should then be placed on paper towels to absorb any excess water, and allowed to cool for at least an hour. The boiling will have removed all of the bacteria and other life forms from the rock.
