Fish waste, uneaten food and dead plants quickly form a sludge layer on the bottom of the aquarium.
The balanced blend of purification bacteria and biologically active enzymes in sera filter biostart breaks down sludge and thus starts the further breakdown of pollutants in the filter.
sera filter biostart is the ideal partner for sera bio nitrivec, which takes up its work just after sera filter biostart. Together, both products ensure clear and healthy aquarium water.
Being a high performance filter material, sera siporax Professional creates ideal conditions for sera filter biostart and sera bio nitrivec.
Directions for use: Shake well before using! Do not overdose the concentrate! Add 5 ml sera filter biostart per each 200 liters (52.8 US gal.) of aquarium water once weekly. Pour the product directly onto the filter sponge. The efficacy of sera filter biostart is even improved if there is highly porous material such as sera siporax present in the filter.
Store in a cool place or refrigerate after opening! Keep out of reach of children and pets! The smell is specific to this product.
