Im looking to see if anyone has a list of aquarium safe rocks that wont chance my water chemistry. Im not fond of going to a pet store so im off to the local landscaping yard to see what they have. Rocks like fieldstone, granite ect. any help would be greately appreciated.
here is a basic list if you want more detail just ask. I will not list any granites of meta's because there locality can have a huge bearing on there composition any ways here it is
shales (may become soft depending on age and layering
remember this is just a basic list for any body with a limited understanding about rock composition the rocks listed above are not 100% safe no rock is.
a good method to be a sure about its basic composition is to carry a bottle of 1molar HCL if it fizzes it is leverite (leave it right there) . or find a geologist i hear they will work for shiny rocks and plants
