How you clean aquarium gravel is going to depend on why you are cleaning it. We’re going to outline step-by-step instructions for cleaning gravel in your tank, new aquarium gravel, used aquarium gravel, and gravel that was in a tank with sick fish.
There are multiple reasons you may need to clean aquarium gravel, from the ordinary to the abnormal, but you do have options to make sure your gravel is clean and safe for your aquarium. It’s extremely important not to use any cleaning chemicals other than the bleach solution described above for cleaning your gravel. Fish and invertebrates can be extremely sensitive to certain chemicals and using things like bathroom, countertop, or glass cleaners can have disastrous results.
If you feel that your gravel or tank has been cleaned using cleaning solutions, it can be difficult to eliminate all traces of these products and it may be safest to replace your gravel. If you choose not to replace the gravel, ensure it is thoroughly cleaned and rinsed to keep your tank safe.
