For the last 4 months, our islands de-sal water plant was down for repair.
We flushed toilets with sea water, carried cleaning and drinking water from a small well down the street, and our bath tub, was the Pacific.
During the last two months, the level of the 180 tank dropped so low, the overflows to the sump was un-useable, so no filtration at all, no water changes, and make up water was only available when it rained.
The only water movement came from a small air pump.

No fish were lost (tank contained 12 four to five inch cichlids, 2 similar size tetras, a Pleco, a few shrimp, and a 6-8" Eleotris goby).
I attribute the lack of deaths to heavy planting, and low stocking level, compared to tank size.
I fed very sparsely, maybe once every 3 days, to reduce nutrient load. Lots of leaves fell in the tank, and tannins were high, turning the water tea color brown
The water came back on last week, sump is now working, and I'm back to doing daily small water changes.
