If you've noticed white particles floating on top of your aquarium water, don't panic! In most cases, this is just a harmless build-up of minerals and salts from the water itself. However, it's always a good idea to check with your local fish store or vet to rule out any potential health concerns.
One of the most common causes of white particles in aquariums is salt creep. This happens when evaporated water leaves behind mineral deposits, which can then accumulate on surfaces like glass or filter media. While salt creep is usually not harmful to fish, it can be unsightly and difficult to remove. If you're concerned about salt creep, there are a few things you can do to prevent it:
- Use an aquarium cover to reduce evaporation
- Rinse new aquarium components thoroughly before adding them to the tank
- Avoid using products that contain salt (like some types of dechlorinators)
