I'm one of the curious ones and like to see and learn what others are doing that is not the norm. Whether I condone, agree, or disagree with it has no bearing on my level of curiosity.
i disagree there are many plus's and minuses to both way's but a reasonably large tank can be run very sucessfully with no changes the bigger the tank the more chance you have you can only do this with planted tanks and with a wide veriaity of plants some plants do diffrent jobs
any switched on enthusiast will know that water changes are better but here is the thing
it can be done
it can be done to have not just healthy fish and plants but fish and plants that thrive
titled this topic for none water changers because he has heard and understands what is the PRO'S and CON'S are
i think he is after tip's for doing it this way so like me with some of my friends that just wont do them unless i go and do it myself so i dont i just recreate an enviroment where they and not need it, of corse they would be benificial to some extent but not needed which is what he asked for
other wise he would of put the title as can i run a tank without changes
the smallest tank i have run like this is a 100 litre i would not do this again with anything smaller than 150litre as the 100 kept fish healthy and never had a problem but you could just and i do mean just tell the difference in the fish i had to look for minute signs of stress the avrg aquaticst would never notice
i now only run my 350 litre like this well i change abouts 20 litre every month so its as good as none and wont stress the fish
but what i was a kid my dad had a huge 800-1000 litre tanks which had no changes for 10 years + never had problems with ammonia nitrite nitrate ph kh or gh the emviroment was stable something far too many can not recreate
any other questions JDM just ask
the only thing i will say is if you or anyone else runs a tank this way do no use ammonit nitrite or nitrate up or down if you do need to just change water the enviroment is not stable enough
