Gel Filter Starter Balls (100+)


100+ Gel filter balls
Gel filter balls are the most efficient way to seed a new filter with beneficial bacteria as they dissolve slowly and release a measured dose of live bacteria into the filter. Simply add to the filter media after filter maintenance or when adding new media.
Use a minimum of 1 ball per 20 litres to seed new filters. You cannot overdose with this water treatment.
Please note the filter starter balls contain freshwater bacteria. If you have a marine tank you will need the Pure Reef Balance to set up the filter - also available from this site.

Gel Filter Starter Balls Brilliant product.

I got a free sample of this product with my first order of Bio Gravel, I love the face you can put thees directly in you filter and they stay there just where they are needed, I've spent hundreds of pounds over the years on all kinds of filter starting Bactria additives and have never seen the fast positive results this product gives, infact I was so impressed I ordered 100 more for top ups during filter maintenance.
