So what is a "Nano" tank?

[cymaster007]

Seeing so many tanks average out to 100g + these days, I have been wondering what is really still considered a "Nano" tank?
Even on the nano-reef forums you see people with 100+ tanks. I know it all depends on different point-of-views. When I first started the hobby I thought 12g and below was a nano.
After keeping a 34g cube in the office and using all the chibi nano-equipment (tunze nano skimmer etc) I almost consider 50 and below nano now....

Quantitatively speaking- nano is defined as a billionth in size....

What do you guys think? Should it be redefined? What should the limit be to define a nano tank? What is too big or small?

Nano reef tank?

Or Nano Reef Tank (compared to some others we have seen)?

I think most in the hobby view "nano" as 34 gallons or smaller.

I am almost inclined to consider everyone who has a tank smaller than mine as keeping nano tanks-

Who has the biggest tank here anyways?

I wonder who has the smallest?

I remember a thread on NR a while back that said a 40 breeder or smaller qualified as a nano. I suppose it is somewhat arbitrary in any case...all of our tanks are "nano" compared to what we are trying to reproduce.

 

[cymaster007]

Thats a good point....the ocean trumps our tanks all into nano tanks
Ive added a poll-

Less than 34 is a nano... I have a 24 nano cube..
Also I thought I saw someone have a thread the other day on here and he had a 1 gallon pico tank...

Since were getting all quantitative and serious, I decided to do a reference. According to Garrison(2005), anything less than 1.37 cubic kilometers is by definition a "nano tank".

"The average depth of the ocean is about 3,796 meters (12,451 feet), the volume of seawater 1.37 billion cubic kilometers."

However, we abide by the ever changing vernacular of our time. Given the predominance of "large" systems in todays hobby I would be inclined to agree with the previous delineation of 40 gallons. I generally follow the following guidelines:

0-40 gallons- Nano system
40.01-100 gallons- Small system
100.01-200 gallons- Large system
200.01-1000- Very Large system
1000.01-greater- (open to suggestions)

What we may consider a very large system may very well be considered a large system before long, a large considered a small, and so on...

The question I would like to ask is:

What is considered a "Pico tank"?

Are pico tanks and nano tanks the same?

Great question! Picos are supposed to be the next smallest size class after Nanos...but where is the dividing line?

 

[Demonkegman]

indeed...

Skeet skeet skeet, just my suggestion

I think they make 5 gallon pico tanks, so maybe anything under 5g?

 

[gumbii]

perhaps...

 

[cymaster007]

I guess you could keep something alive in a shot-glass if you really wanted to and could do the water changes correctly.... (PH/Temp shock)
I just might try this out with some zoas. Have a shot-glass colony?

 

[Clockwork John]

My understanding is that a pico is anything under 5 gallons.

 

[solitude127]

Do you feel pico and nano tanks are easy to sustain healthy livestock as compare to a 100g system?

No way, the nano tank I was keeping had a much stricter maintenance routine than my 125g. The smaller tank got spikes in phosphates and other things from a single mysis cube and was barely measureable on the 125g
