Fishless cycling

Fishless cycling can reduce the chance of fish loss resulting from insufficient populations of nitrifiers.

Allowing ammonia to be converted to nitrite and onto the less harmful nitrate minimizes stress and injury to aquarium fish.

[3] The same study found Seachem Stability, API QuickStart, Imagitarium Biological Booster, and Fluval Cycle to perform no better than using no products, at least over the first 14 days.

[5] The most significant advantage of fishless cycling is that it can reduce fish loss due to ammonia and nitrite spikes.

[6] However, care in adding ammonia for fishless cycling must be used, too high of an ammonium concentration can kill nitrifiers.
