Well i keep lights on only for 6hrs (on timer). Had pirchased bleached toadstool and bleqched gbta. Both recovered beautifully. no waterchanges at all, its been 7mnths i guess. Every sunday im supplementing the tank with seachem reef plus, seachem phyto, adv cal and reef builder. Everting i dose is half the recomended dosage. The coralline is pickingup superfast.From experience, there will always be an outside source. It is impossible from the strictest standards. You need light for one. A variable that automatically negates a true self sufficient tank. I believe water changes or supplements would be another negating factor. The nutrients have to come from somewhere. As far as not feeding fish and no water changes are concerned then yes, it is possible. Would need large quantities of water, light, macro algae and additional supplements to sustain as such. I had a 75gal that lost power for over a week. I didn't lose anything and rarely fed the fish then or otherwise but in the end it simply would not maintain itself under those conditions. Even the ocean gains nutrients through sunlight at the very beginning of the system...
You keep mentioning dsb , what is thatI think a good balance of fish, rocks, dsb and macro algae is required for this setup. Thats why i posted it.
Deep sand bed. But in sump, not dt.You keep mentioning dsb , what is that
Would be great.planning a system like this,as i am about 800 km to closest coastline,will put pics as i go along
Jaubert is sally joe system?Anyone ever heard of the Jaubert system? Its almost self sustaining
Yes, tge plenum method, sally joe uses same method i guess. I learnt about seachem dosing reading it.
This thread was made looking at loads of different types of systems like:The only long-term self-sustaining reefs are located in oceans or seas.
20+ years ago, when I was a teenager and worked with tank maintenance, two customer's tanks were "sled sustainable" for 1 and 2 years. They weren't designed to be self sustainable, but they eventually got neglected and still thrived.
They were both 700l+,SPS dominated, with DSB, 2x400w MH, ato, refuting, skimmer and ca reactor.
Before being neglected, they were solid systems, packed with fish and thriving colonies.
These guys stopped doing any maintenance, apart from refilling the ato container and the result after one year was amazing to watch.
The first year is natural selection, some fishes died some thrived and even reproduced(bangaii).
Most SPS grew up to gigantic sizes and eventually montis(all types) started outgrowing all other corals.
Second year was even more interesting, with colonies so big, they were growing on the front glass.
So, it is possible to run tanks in "auto mode", but the result is what most people consider beautiful.
In their cases, I am certain what made it possible was water volume x bioload, being mature tanks and running on a ca reactor.
...and then old tank syndrome took over?
there is no health reason for cleaning the glass

Hey All, I am new to this forum thing
Anyone ever heard of the Jaubert system? Its almost self sustaining
it requires an air stone so that po4 and no3 is properly broken down - no need for a sump (if this is done inside the main tank) - just wave pumps and an airstone
