a very good article, shows some good graphs and dispels some myths. a very good read IMO. writer is not biased in anyway, takes his conclusions from mathematical results. certainly has got me thinking about my water chemistry. and if you dont read it in its entirity, dont jump to the conclusion that "water changes aren't needed". its simply shows how many water changes are required to replace trace elements and remove nutrients...

Good article Chimera, I've seen it before.

Funny how it's just common sense but often not really understood.

Like advice being given that someone with nitrates through the roof should fix it by doing a series of 5% waterchanges! Yes True! I saw that advice offered.

yeah biggest misconception certainly is the number of water changes required - gotta remember theres little point if what you take out you're putting back in in a smaller quantity for replenishing trace elements, or larger quantity if you're removing nutrients

interesting article thanks for the read!
