What's The Longest Fish-In Cycle Recorded As?

[G-skrilla]

What's the longest fish in cycle and the longest fishless cycle known to man?

 

[VaegaVic]

The oceans.
550 million years.

We have had several members go well over 100 days here. I think that WD actually keeps track of who has the latest claim to longest cycle.

Wow what's the gallon amount on the oceans? The way I've started off it might be 550 million years for mine too.

Not counting the first month I used biomature but when I had to re start in about 10 days or less I'll have my 100 day anniversary! Counting the biomature im well over sucks but not to worry. I'm sure there will b longer. Must b a point you say right I'm changing to fish in! Although my readings are getting there but how long who knows!!

wasn't waterdrop's the one that wouldn't cycle?

WD has advised many people on doing a fishless cycle but I doubt he had a long one himself. Like me, he has mature tanks so new ones take very little time to cycle. There is nothing like the jump start a mature tank can give to a new one.

Yes, we've had some cases work their way through the months here in the beginner section where some major problem or another has make the time look doubly long, in the range of 180 or 200 days. But in each of those cases, it's not the fishless or fish-in cycle that is the culprit but the problem (such as a tank breaking half way through or the person dumping a lot of some problem substance in during the early stages before they had any advice here.) In each of those cases if one examines what might fit into a description of simply a long problematic but valid cycle, they would usually look like about 70 to 120 days or so at the worst. The vast majority of cycles play out in about 40 to 70 days in my rough estimation, if they are good cycles (not to be confused with the MM (mature media) and "Clone" cycles, which play out often in 7 to 15 days.) In my experience there is little appreciable difference between fish-in and fishless overall times except of course that you have less feedback with the fish-in and so are blissfully unaware some of the time, but frustratingly changing water a fair amount of the rest.

The subject of the volume of natural waters was brought up in jest but of course every good student of the Nitrogen Cycle at some point ponders the gravity of this topic. The difference between what nature is able to provide in these vast volumes and what we are not able to really provide, but instead attempt to simulate in a feeble way, is of course really behind all that we talk about. I find water volumes to be quite deceptive. Standing in one's mud waders in a collection pool along some creek way out in the back woods, we see an example of the sorts of natural places our little freshwater fish come from. On some level it looks small, but in fact it can be thousands upon thousands of gallons and to top it off, it is constantly refreshed in most cases and we must always remember that water data we see taken from a spot like this (often taken by us to mean a sort of "ideal" for a native species of fish) is in fact an "instantaneous" reading and does not represent the same "static" situation as respresented in our tanks with a fixed body of water constantly recirculated.
