The chiller pump burned out, taking the climate system offline, so the whole system has been left venting to manage humidity and air circulation while the repair is pending. That venting means water is leaving through evaporation instead of recondensing. Josue tops off by pouring water into the Lowland Meadow, the highest point in the system, and lets it travel downhill through the substrate to the Freshwater Lake, the same base-flow process that tops off real lakes between rainstorms. Isopods, Surinam Cockroaches, and Common Crypt Ants living in the Lowland Meadow substrate surfaced as the water moved through the ground.
