The Crystalline Purity of the Asphyxiating Air (The Denied Oxygen of the Futile Blind Filter):

*Caridina cantonensis* requires frighteningly high oxygen levels. A normal internal or hang-on-back filter IS NOT ENOUGH. Professionals exclusively use large SPONGE FILTERS driven by an air pump. This system performs three vital tasks: 1) It creates massive surface turbulence that injects oxygen (crucial at acidic pH), 2) It provides an endless pasture of biofilm for the babies to graze on, 3) It physically prevents the newborns from being sucked in and shredded by a mechanical impeller.

The Ticking Time Bomb of Exhausted Soil (The Silent Mute Futile Blind Ammonia):

In a Caridina tank, the active soil is THE HEART of the system. It absorbs KH and keeps the pH acidic (below 7). Thanks to this, deadly ammonia is converted into the less toxic ammonium. BUT BEWARE: after 12-18 months, the soil EXHAUSTS ITSELF. No longer able to buffer the acidity, the pH rises. In A FEW HOURS, all the accumulated ammonium instantly transforms into highly toxic ammonia, causing a TOTAL EXTERMINATION of the colony. Be prepared to replace the soil every year and a half.
