Exotic Tropical Fish has a range of suitable rocks for use in aquariums. We recommend you ask our advice on which rocks would best suit the type of fish you are keeping. These rocks can also be used for decorating your reptile tank too!
We recommend you avoid coral, sea shells, dolomite and limestone based materials. These will release carbonates in the tank raising its pH buffering capacity. A simple test to determine if your gravel is inert and will not affect the pH is to drip an acid such as vinegar on the gravel. If it foams or bubbles it is not inert and will leach carbonates and affect the pH.
Come down and have a look at what we have in stock - we're sure to have something to suit your needs.
