Solution: Thoroughly rinse the sand until the water runs completely clear before adding it to the aquarium.

FAQs

Is pool filter sand safe for all aquarium inhabitants?
While generally safe, it's crucial to thoroughly rinse the sand before use to remove any dust or manufacturing residue. Always research the specific needs of your fish and plants, as some sensitive species might react negatively to the slight pH shift some sands can cause. Observe your tank closely after the change for any unusual behavior.
