FAQs about Aquarium Cleaning Supplies
There are ways to clean your tank without harming your fish. Such as replenishing 20% of the water at a time, or scrubbing the sides of the tank with a magnetic brush.
The right aquarium water care depends on your tank. Freshwater and saltwater tanks have different needs. At Petco we have conditioners, neutralizers and other water treatments to help clean your tank.
Every fish tank requires different maintenance. It’s best practice to replenish a quarter of the water in your tank at least once a month to help maintain pH levels and remove excess waste.
