No, Cycle is generally regarded as a complete waste of money. Are you trying to cycle (ie, mature the filter), or just adding it with every water change to a stocked tank?
just adding cycle, i mean ive had dese 5 tetras for like 3 weeks now, they seem to be doing fine now, jus adjusted to the aquarium..
im adding cycle everyweek, and aqua plus on every water change?
