Evolution Aqua PURE+ Aquarium Filter Start Gel – Kick-Start Your Biological Filtration

Setting up a new aquarium is exciting, but establishing a healthy biological filter is one of the most important steps before introducing fish.

Evolution Aqua PURE+ Aquarium Filter Start Gel is a concentrated live bacteria treatment developed to help establish beneficial bacteria directly on aquarium filter media.

Unlike bacterial treatments added to the aquarium water, PURE+ Filter Start Gel has a specially formulated gel consistency that helps it stick to filter media, placing beneficial nitrifying bacteria where they are needed.

This helps accelerate the biological maturation of new aquarium filters and supports the conversion of harmful ammonia and nitrite.

Why Choose Evolution Aqua PURE+ Aquarium Filter Start Gel?

  • Live beneficial bacteria – contains a concentrated culture of nitrifying bacteria.

  • Fast-acting gel formula – designed to adhere directly to filter media.

  • Supports new aquarium cycling – helps establish biological filtration.

  • Helps process ammonia and nitrite – supports the aquarium's natural nitrogen cycle.

  • Ideal for new filters – particularly useful when starting a new aquarium or replacing biological filter media.

  • Easy direct application – simply pour the gel onto your filter media.

  • 250mL bottle – treats aquarium systems totalling up to 2,500 litres.

How Does PURE+ Aquarium Filter Start Gel Work?

A biological aquarium filter relies on beneficial bacteria to process waste produced by fish, uneaten food and other organic material.

During the nitrogen cycle, ammonia is converted into nitrite and then into nitrate by different groups of beneficial microorganisms.

New aquarium filters generally take time to establish sufficient populations of these bacteria.

PURE+ Aquarium Filter Start Gel helps introduce nitrifying bacteria directly to the filter media, encouraging faster colonisation and biological filter maturation.

Because the gel adheres to the media, it provides a practical way to seed the surfaces where biological filtration takes place.

Ideal for Starting New Aquarium Filters

PURE+ Aquarium Filter Start Gel is particularly useful when:

  • Setting up a new freshwater aquarium

  • Starting a new canister, internal or other biological aquarium filter

  • Replacing old biological filter media with new media

  • Establishing a new biological filtration system

It can help reduce the time required for bacteria to colonise filter media, but it does not guarantee that an aquarium is immediately safe for fish.

Always confirm that ammonia and nitrite are at safe levels before introducing livestock.

How to Use Evolution Aqua PURE+ Aquarium Filter Start Gel

Follow Evolution Aqua's manufacturer instructions:

Step 1 – Shake the bottle

Shake well before use to ensure the bacterial culture is evenly distributed.

Step 2 – Apply directly to filter media

Unscrew the cap and pour the gel directly over your biological filter media.

Apply enough gel to coat the media, using a maximum of 125mL for the first application.

Step 3 – Repeat after 14 days

Repeat the treatment after 14 days, using the remaining gel as directed by the manufacturer.

Step 4 – Maintain oxygenation

Evolution Aqua recommends additional oxygenation using an air pump and diffuser when using the product.

Step 5 – Monitor water quality

Regularly test ammonia and nitrite, especially before introducing fish.

Important UV-C Instructions

If your aquarium operates a UV-C steriliser, switch it off during treatment and leave it switched off for 12 hours after dosing.

This helps protect the introduced bacteria during application.

Does Filter Start Gel Instantly Cycle an Aquarium?

No. Although PURE+ Aquarium Filter Start Gel is designed to accelerate filter maturation, the aquarium still needs to establish sufficient biological filtration to process the waste produced by its livestock.

The time required depends on factors such as water conditions, oxygen availability, filter media and the amount of ammonia being produced.

Continue testing the aquarium throughout the cycling process and introduce fish only when the system is ready.

PURE+ Filter Start Gel vs PURE Aquarium Balls

Evolution Aqua offers several beneficial bacteria products, but they serve different purposes.

PURE+ Aquarium Filter Start Gel

Designed primarily for starting new biological filters and establishing bacteria on new filter media.

PURE Aquarium Balls

Designed for regular maintenance of established freshwater aquariums, helping support biological balance and water clarity.

If you're setting up a new filter, PURE+ Filter Start Gel is the more targeted product.

Aquarium Haven Tip

Apply PURE+ Filter Start Gel directly to your biological filter media before putting a new filter into operation.

This helps position the bacteria where they need to establish, rather than simply adding them to the aquarium water.

For a new aquarium, test ammonia and nitrite throughout the cycling process. Even when using a bacterial starter, patience and regular water testing are essential for creating a stable, fish-safe environment.
