filter-start Bacteria Aquarium 473 ml - gel Filter Instant Activation bacteria, form, fast activation, stable nitrification, against mulm, ammonia, nitrite, freshwater, saltwater

ARKA Gel Filter – The bacteria gel clings directly to the filter media, where the beneficial microorganisms settle quickly and give instant biological activity in the filter of freshwater and marine aquariums. Shorter cycling time – Cuts the filter cycling time significantly, prevents instability after filter cleaning or a media change and quickly restores biological activity in the filter even after heavy load. Less sludge in the filter – Organic waste is broken down faster, filter media stay cleaner and the intervals between cleanings become longer. The gel also supports nitrate reduction in the filter. 473 ml for larger tanks – The large bottle offers plenty of reach for medium to large aquariums, breeding tanks and regular care and supports the breakdown of ammonium and nitrite. Easy to use – Shake before use, wet the filter media in lines or dots and leave porous media to work for 15–30 minutes. Repeat at every filter cleaning. For aquariums only, do not drink.
