Explore aquarium cycling and bacterial care

Aquarium bacteria starters: browse Seachem Stability, API Quick Start, Fluval Cycle, Dr Tims One and Only, Fritz Zyme 7 and 9, and selected Dymax and Aqua-Pics formulas.
Fishless cycling supplies: compare Dr Tims ammonium chloride and Aqua-Pics Cycle-Right bacteria food. These provide a cycling input rather than being bottled bacteria themselves.

Bacterial maintenance products: browse Dr Tims Waste Away and Eco Balance, Fluval Biological Aquarium Cleaner and other products intended for ongoing aquarium care.
Pond care: selected listings include Seachem Pond Stability and Evolution Aqua Pure Pond Bomb. Choose products specifically labelled for your pond application.

Choose a formula for your tank

Match the product to your aquarium type, water volume and purpose. Freshwater, marine and pond formulas are not automatically interchangeable. For example, compare Dr Tims H2O-PURE and REEF-PURE options, and Fritz Zyme 7 freshwater and Fritz Zyme 9 saltwater products.

Starting a biological filter and managing accumulated organic waste are different tasks. This collection also includes conditioners, clarifiers, nutrient-management media and other related products; not every listing is a bacteria starter.

Follow a test-led cycling plan

Use the current product label and cycling instructions, and monitor ammonia and nitrite with suitable water tests. Adding a bacteria starter is not, by itself, confirmation that an aquarium is ready for livestock. Avoid relying on a fixed cycling time or water clarity alone.

Ammonium chloride and other fishless cycling inputs should be used only according to their fishless cycling instructions, not as routine additives to an occupied aquarium. Check dosing, storage requirements and any directions about filtration equipment before use.

Compare pack sizes, labelled treatment volumes and freshwater or marine applications on individual listings. Check availability and clearance notes before ordering.
