I have some left over coral rock from my saltwater fish tank. Can I use this in a pot with bonsai plants? If so, any recommendations? Thanks.

I would not recommend using coral rock in any bonsai affiliated project. Saltwater coral rocks contain calcium bicarbonate which has a toxic quality to the soil, it would also be a constant battle to control the soils PH as it will cause a high alkalinity the same as if Lime stone was used. Furthermore it will cause unfriendly soil conditions by interfering and eventually preventing the tree from absorbing essential nutrients and trace elements from the soil.
