Frequently Asked Questions

AI
Yes, most gravel should be rinsed thoroughly in a colander with dechlorinated water. This removes fine dust and debris that can cloud your water and irritate your fish.
Gravel provides more surface area for beneficial bacteria to grow, which helps with biological filtration. Sand is better for bottom-dwelling fish that dig, but it can be harder to maintain in some setups.
No. Many garden stones contain minerals or dyes that can leach toxins into the water or alter the pH levels, which can be fatal to fish. Always use gravel specifically labelled as aquarium-safe.
