Seems like its a fad to say "You don't need to do weekly water changes" Well,no and you also don't need to feed your fish everyday or live foods or...but let me tell you, things are BETTER with weekly water changes,well fed fish and live foods if possible.
I mean have you read anybody say weekly water changes were bad for their aquarium? No,you haven't.-lol.
I mean the idea of not having to do water changes only works for very hardy fish,or a very light load of fish and even then,a partial change would help. You show me an aquarium that has gone weeks with no water change and I say to that "20% a week would be better". And it would be.
Your filter isnt likely to make water as pure as what you drink. You could use carbon and with UV lights and a great sump filter have high quality water...and yet, a weekly water change is still good. I mean you have to clean the tank about once a week anyways..so your great filter and plants makes it ten percent. But that 10 % helps.
Like nature does..replace old water with new and she does it 100% of the time.
