6 week vacation without water changes

Hi.  I am loooking for advice on how to give the koi indoor tank the best chance when I go for vacation for 6 weeks.
I plan not to do water change during 6 weeks and feed the kois by automatic feeder.  Do you think its possible?
The pond is 45 us gallons.  I am thinking of putting the whole bottle of the cycle product to give the pond a good chance of keeping the ammonia and nitrate nitrite as low as possible.

The Ammonia is 0 but nitrite is 0.3mg/L.

Is this an inside pond or outside at the moment?

How many fish do you have in this tank, how big are they, what kind of filter you have?

See the post under Freshwater Beginners for these 2 questions.

There ya go Tom, you must not have seen it

 

I'm going to merge the two topics. When the same topic is posted in several places it's hard to give good answers and keep them together.

I have an Astro filter.(model 2208).This filter has the capacity suitable for 80 US Gallons and my tank is 45 US Gallons.  I  don't have any plant in it.  The tank has enough oxygen I guess because the kois don't go to the surface to breath.  please give me advice what to do before going to vacation.

 

First off, the tank is overstocked.
Second, 6 weeks with that many fish in that small of a tank and no water changes, you are more than likely to come back to dead fish. If not a crashed tank.
My advise would be either have someone come in and do a change or start up another tank and spread the fish out.

I honestly thought that my tank is not overstock so far because of the rule of 1 inch of fish for every US gallon of water.  I have 6 kois of 6 inches each, and that is suitble for 36 US gallons of water but the tank is 45 gallon so I thought it should be OK.   When the kois become bigger I plan to have a big pond for them.
Does it exist a automatic water change machine?
Looking forwards to your comments.

 

The inch a gallon rule is faulty.
6, one inch long neon tetras do not produce the waste that a 6 inch koi does.
A more accurate measurement is biomass.
With biomass, you consider the volume the fish has, not just its length.
Yes, there are automatic water changing machines.
They start in the hundred dollar + range and go up from there.

How do you use the Biomass rule? For my situation how many kois should be safe for the system to work properly?

 

One.
And that for only about a year, till the koi outgrows the tank.
