The Importance of Keeping Your Gravel Clean
- Remove debris from the bottom of your tank – Gravity is always at work in your aquarium, and everything ends up in the gravel at the bottom of your tank – food waste, fish waste, and plant waste. Gravel that isn’t properly cleaned will eventually turn into a sludgy, slimy mess, and pollutants will take over your tank.
- Improve your tank’s chemistry – When pollutants build up in your tank, there will also be a build-up of nitrites and ammonia, which will negatively affect your tank’s chemistry. Harmful bacteria and pollutants will add to the problem, leading to a decreased immunity of your marine life.
- Make your fish happy – Pollutants and toxin build-up in your gravel will contribute an unhealthy balance to the bacteria that thrive in your tank. Not all bacteria is bad for your aquarium — some bacteria will help maintain a healthy environment for your marine life.
- Improve the look of your aquarium – You probably wouldn’t even consider keeping fish if you didn’t enjoy the aesthetics of your aquarium. Keeping your gravel clean is one of the easiest things you can do for a lush, beautiful aquarium, teeming with fish.
