benefits of PWC

[cheeky_monkey]

Can anyone link me to a good well written page on the benefits of regular PWC?

I have several people ask me why I do regular PWC and I'm growing tired of explaining myself over and over again when usually I'm met with laughter and the usual "well I don't do that and my fish are fine" spiel. I want to be able to just give them a link and only reply if they genuinely ask further information.

Thanks in advance

I just tell them if asked, to keep my fish alive, the tank clean, me happy and water parameters under control. If they persist I just tell them that I had already painted the inside of my mailbox and rearranged my sock drawer so a water change was next on the list of things to do.

Thanks for the giggle Convict.
Any links or info relating to the amount of bacteria in the water versus the filter media and tank contents?
