Wow! I'd imagine oxygen depletion, even with so many plants but I guess you said you have a small airpump too, did you happen to get a chance to read your parameters before adding water when it came back on? I'm curious of your parameters were still good or if they were borderline at that point...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.

This is much easier.I can't even keep plants alive in a conventional fishtank..
The same problem I have.I can't even keep plants alive in a conventional fishtank..
Very interesting. I'd still do water changes, but super low nitrates is nothing to sneeze at. I've got pothos but it's not performing as miraculously as some have made out. Maybe my tank water isn't ideal, I do have high pH and hard water.Yes, JH, you can use Pothos, but the plant is too viney and the root system doesn't grow thick enough to make a dent in the nitrogen that's produced in a large tank with a large fish load. The boys at NASA haven't used Aglaonema or they'd never go back to Pothos. The "AG" plant thrives in low light and stays on top of the tank. You only need a very small bacteria colony to use the small amount of nitrogen the fish produce at night when the house plants rest. Don't waste time on trial and error. Go to the nearest Lowe's and get a bunch of Chinese evergreen for a few dollars. Rinse off all the potting mixture and immerse the roots in the tank water with the leaves above. The tank water will stay near nitrogen free and you'll never have to do a water change.
