Secure your complete long-term water care supply with the Biologica Eco-Refill Bundle. Designed for spa owners who already have their standard Biologica aluminium bottles, this mega-value pack contains all four essential 500ml concentrates.

Because a single 500ml eco-refill yields the equivalent of five standard bottles, this four-piece bundle delivers an incredible 20 bottles worth of premium, natural spa treatment in one compact delivery.

You receive:

• 1x Spa Alchemy Concentrate (500ml)

• 1x Restore Filter Cleaner Concentrate (500ml)

• 1x Purge Pipe Cleaner Concentrate (500ml)

• 1x Brilliant Surface Cleaner Concentrate (500ml)

By choosing the concentrate system, you drastically lower your cost per use, free up space in your spa cabinet, and keep 16 bulky plastic bottles out of the environment.

Mixing is simple: just pour the required amount of concentrate into your empty ready-to-use bottle, fill with fresh water, and maintain your crystal clear, natural spa exactly as normal.
