Frequently Asked Questions (FAQs)

1. Which is better for fish tank sand or gravel?

Gravel is the better choice for most freshwater aquariums. One of the major benefits of gravel is that it allows water to flow through it, preventing the buildup of amoebas and bacteria in the substrate. If allowed to build up for too long, these can sicken your fish and lead to an accumulation of aquarium mold.

2. How thick should gravel be in aquarium?

It is recommended that fish tanks that have a capacity of 55 gallons and below should be provided with a layer of gravel that is about 2 inches deep.

3. Can you use all purpose gravel in an aquarium?

The principal danger of using your own outdoor gravel and stones in an aquarium is the possibility that they contain calcium, which can. But before testing, make sure to also wash the stones thoroughly to remove all loose grit and contaminants.
