Natural Rapport Aquarium Gravel Cleaner — Liquid Biological Cleaner for Tanks

Effortless care for cleaner water

Natural Rapport Aquarium Gravel Cleaner is a liquid, biological cleaner designed to work with your existing aquarium setup. It introduces healthy bacteria that gradually break down waste, uneaten food, and odors trapped in the substrate. No vacuum, siphon, or pump is required—simply pour and let nature do the work for clearer water and a more pleasant tank environment.

How this helps your tank over time

Beyond immediate cleaning, this formula is designed to extend the time between full water changes and manual gravel cleanings by reducing organic buildup in the substrate. It also helps address overfeeding by breaking down excess food before it decomposes, which can contribute to calmer water chemistry and better overall tank conditions.

• Natural bacteria-based action targets waste and odors within the gravel, sand, or other substrates.
• Non-chemical formula reduces reliance on traditional cleaning routines, potentially easing routine maintenance.

• Reduces the buildup of ammonia and nitrite; supports control of nitrate and phosphate in many setups.
• May contribute to clearer water and a more consistent tank appearance over time.

What you can expect in your aquarium

This cleaner treats up to 960 gallons per bottle and is suitable for freshwater and saltwater tanks. It is intended for use with a wide range of inhabitants including fish, invertebrates, live plants, and corals. The product works with various substrate types, including gravel and sand, without requiring removal of substrate prior to dosing.

Made in the USA with natural ingredients, the formula avoids harsh chemicals, phosphates, dyes, or alcohol. For a comprehensive approach to aquarium care, pair with an all-in-one water conditioner designed to complement biological cleaning efforts.
