César Riveiro de la Peña is the creator and author of MACI, the Integrated Aquarium Circuit Framework.
His work comes from more than two decades of direct observation, long-term aquariums, and documented experimentation. MACI is not a recipe or a closed routine: it teaches the aquarist to read the aquarium as a living system before intervening.
