Fyzikálno-chemické parametre v morskom akváriu

More poskytuje relatívne stabilné prostredie pre morské živočíchy. V morskom akváriu toto prostredie vytvárame my. Čím stabilnejšie prostredie vytvoríme našim chovancom tým budú zdravší a vitálnejší. Prílišné kolísanie chemicko-fyzikálnych parametrov neprospieva rybám ani bezstavovcom. Parametre sa snažíme udržať v dole uvedených hodnotách.
