• Is it possible to leave water in the aquarium?

  • Nicholas

In general, the situation is as follows. There are two aquariums in the system (a third sump). The small one had fish and a shrimp, which have grown. I transferred them to the main aquarium. To reduce energy consumption, I want to turn off the return, flow, and light in the small aquarium, as well as reduce noise. The question is: Can I leave the water in it in this situation, and if new inhabitants arrive, can I connect this aquarium to the system with the existing water?

No. We need to at least leave some current or provide aeration.

So I'll leave it as it was, just won't turn on the light. The system will be more than 60 liters.
