Self Sustaining Nano-Tank

Hi Friends,

I am new to keeping an Planted Tank , I am wondering is it possible to have a self-sustaining nano-tank?

Currently i have a 55 G tank, with DIY CO2, and the plants are thriving. But i am wondering is it possible to setup a nano-tank with CO2 from Fishes and 50 % water change regularly...

Is it possible?

Most people who end up with self sustaining tanks just get lucky. It's difficult to set one up from the start.

100% self-sustaining would not be possible AFAIK.

NPT/Walstad-style tanks come close tho. I'm just getting back into the hobby but my previous tank was a 10gal NPT. Plant/fish/shrimp respiration, fish/shrimp waste, decomposing plant matter, and fish food provided CO2 and fertilizer. No water changes at all; just top-offs. No filter even. It was a great tank that required very little maintenance.

That being said, I still fed the fish/shrimp every few days, topped-off the water twice a month, and pruned plants once a month or so.

Nice!!!

How much Shripms/Fishes you had, how much would be enough to grow one Tiger Lily and dwarf grass to grow?

My Tank is a Open 5G Bowl, with a wide moth; so a Tiger Lily can be planted and coaxed to Bloom

I was planning to have Crystal Red Shrimp and River Stream Loach...

IIRC, that tank had 1 oto, 5 ember tetras, and a 30+ colony of RCS.

I don't know that it'll work if you just have a tiger lily and DHG. I always recommend a sizable amount of fast-growing plantmass to start off unless you want to grow algae

What are the plants do you have in your tank....

A pic with plant list would be helpful...

Lets say about 10 % of CO2 is dissolved from Atmosphere....
So the remaining CO2 is provided by Fish...

I never took pics unfortunately because it was just an experimental tank. I set it up to see what I could grow and what I couldn't. Every plant I tried grew or at least didn't die. Here's the list IIRC:

Rotala rotundifolia
Rotala sp. 'Green'
Fissidens fontanus
Java moss
Subwassertang
Anubias nana 'Petite'
Lilaeopsis brasiliensis
Crypt lucens
Downoi
Wisteria
Hygrophila polysperma
Marsilea minuta
Hornwort
Duckweed lol

If by "self-sustaining tank", you mean low-maintenance, they can be very easy to set up (as long as you do your research first). The easiest setups utilize rapidly-growing plants with animals that have a low contribution to the total bio-load. If you leave out the DIY CO2, you'll have one less thing to maintain. Upon initial set up, monitor algae and plant growth closely and adjust water/lighting parameters as necessary. For instance, if you see increasing algae growth, consider decreasing your light intensity and doing small, frequent water changes to reduce nutrient levels until conditions improve.

+1 for NPT/Walstad-style tanks

-1 for achieving a successful tank by luck; There's little luck involved - it all comes down to understanding the science of freshwater ecosystems.
