Hi all,

read this from a Chinese article, translated this portion into English.

Aged Water (Lao Hua Shui)

"Mundanely referred to as dead water, it refers to stagnant water that has been stored for a long period of time. Frequently drinking this kind of water has adverse implications for people: for the young and adolesence, it slows down the process of metabolism, it also affects physical development. for the middle-aged and old, it will hasten the ageing process. according to medical research, the increase in intestinal and gastric cancer cases may be linked to drinking this kind of water on a long time basis."

reference: Singapore, Chinese Daily (Morning) or Lian He Zao Bao, 6th Nov 2004

from this article, it spells possible negative implications for our bettas. the problem is it did not define "long period of time". = 2 days, 3 days, 4 days... ??? no idea too though i recall reading somewhere that 3 days seems to be the benchmark. maybe someone can verify this?

the article also stated "stagnant water", which most of us keep as part of the ageing water process. understand that not everyone has the habit of keeping aged water in tanks/containers with water running devices (e.g filters, pumps, bubbling) so this should be relevant material. the idea is to keep aged water always in motion. have also read that keeping living things (e.g other fishes, live plants) in the ageing tank helps too.

just for information.

drinking water has no smell or color.
standing water (for over a week) that its surface is exposed to the open will start to stink!
the first rule for me is "if you cant drink it, don't let your fish drink it"

Plants by the way are the best biological filters ever!
in all of my tanks i keep a fast growing plant that does not need any special requirments of light!

I think they refer to dead water as water that has been lying around for a good while. It builds up anaearobe bacteria which is bad for all animals.

Bettas generally have other needs as they actually are capable of living in dead water.
