Re: [AGA Member] Water question..

["Amit Brucker" <amitb@gtek.co.il>]

Well I do both...
I do have a CO2 system and I do change water every 2 weeks about 25%.
So I add CO2 from both sources....
It would be interesting though changing the water change interval see if
that would effect the water making them softer?
Well its pretty obvious at least in my case that plants do well in hard
water.
My big 'but' is that I always see magnificent planted tanks which are
consist of very soft water.....
So I guess I am being too fanatic ;-)
Thanks for your help .

Amit

plants do better in a KH between 3-8 ?"

characteristics, let it stand in a glass for a day and then check its pH.

the tank. The plants us the CO2 which is in the water. They use it up -
pretty quickly, if they are growing well. Where do they get more, unless you
are constantly adding either new, CO2 rich water from the tap or or CO2 from
some other source?
