Menm si yo swiv bon pwosedi, pòv fètilizasyon ka toujou rive. Pousantaj fètilizasyon ba yo pral lakòz nan lo ki bezwen atansyon konstan, paske nenpòt ze unfertilized (ki nan pwen sa a pa ka distenge soti nan ze fètilize) pral kraze epi redwi kalite dlo a. Sa yo se bezwen plis chanjman dlo souvan. Gamèt ki fètilize mal kapab pwodui pa koloni paran ki ensiste pa chalè oswa polyan.

Even if proper procedures are followed, poor fertilization may still occur. Low fertilization rates will result in batches that need constant attention, because any unfertilized eggs (which at this point cannot be distinguished from fertilized eggs) will break down and reduce the water quality. These batches need more frequent water changes. Gametes that fertilize poorly may be produced by parent colonies that are stressed by heat or pollutants.
