Let's not forget that most aquariums have much higher density of fish per gallon than most natural systems. Plus disease, low oxygen levels, and algae blooms are a normal part of natural systems that we wouldn't want in our tanks.

Exactly ! I couldn't agree more.

Its actually not. Evaporation will remove only water when the whole point of a water change is to remove the stuff that has built up in the water. Nitogen, phospates, carbon, and everything else that adds to the TDS does not evaporate.

Lakes output nutrients in a number of ways: streams, the water table, evaporation, and seeping back into the ground water. Nutrients(plants/aniamls) can also be removed from the system by terrestrial animals. A lake is not its own ecosystem, thats the issue here. It is dependent on the land, geography, and terrestrial ecosystems surrounding it.

.... I'm probably drunk.

This is how I lurk

No example that you would accept exists.
How does that apply to our closed systems?
As a reminder:
Before water change=replacement water+[(buildup)/(fraction of change)]
is where the tank winds up.
So if you do a 10 percent change every 10 days with a 1ppm /day increase results in 100 ppm plus replacement water.
And so newbies do weekly water changes then wonder why nitrates are high.
and people wonder why I have unmeasureable nitrates with no water changes.

our tanks are not a 'closed system', ... water goes in (fine, that's not going to have an effect on open or closed)

any tank where water is removed (not by evaporation) is not a closed system.

like in nature, ... if a lake is being supplied water, and there is no output to remove TDS or any other buildup, ... things are going to become toxic to life in that body of water as any and all water that is added to the system is going to bring in additional material.

in our tanks (those of us who try to maintain a more closed system - no water is manually removed) ... the same situation is going to take place if we are not removing anything.

including plant trimmings, ... if we're not trimming our plants and not removing any water, things are going to build up to toxic levels eventually, ... do i have a guess as to how long this could take, ... well lakes in the world that do this are thousands of years old, ... so ... good question on how long it would take in an aquarium we have at home.

How would we have wondered that ?? Seeing as you've told us you haven't checked your water in a loooonng time ? In fact last I remember you needed a new test kit because yours was very old and you hadn't checked your water in years was it ? (Just going by your own words ..not that nitrates are more then small concern I have with your "method")

True

But it is a matter of degree and I was only talking about the effect of water changes.

So the question is how much closed and now much open?

a 10% weekly water changes is IMHO almost a totally closed system and acts like a closed system when compared to a tank with a constant water change equal to several 100% water changes per hour.

Which is why that equation I submit and is ignored is so important. With the massive water change senerio the tank does become a reflection of what the replacement water is. By contrast with a 10% weekly water change the tank reflects the processes going on in the tank and not the conditions of the replacement water.

To my our job as aquariumists is to provide quality environments to our fish. With water change schedules convienent to aquariumists, those conditions will reflect the tank actions not the replacement water.

maintain Fw and marine system with a strong emphasis on balanced, stabilized system that as much as possible are self substaning.

have maintained FW systems for up to 9 years with descendants from original fish and marine aquariums for up to 8 years.

With no water changes, untreated tap water, inexpensive lighting by first starting the tank with live plants (FW) or macro algae( marine)

Who does 10% water changes every 10 days? Mine are 40-50% weekly, and the only place I see 10% water changes recommended are from petsmart....
