007genie,
I run everything thru the dishwasher with soap.
Only decor such as plastic rocks and nets is being cleansed that way.
No sponges, nor filter material.
Afterward I rinse everything well under running water. I found using this method will eliminate bacteria or parasites from an "illness tank".
Perhaps I have been only lucky so far, but for the hard scape material I feel it has done a good job.
:girl:Heh, Slappy, ...believe it or not. I actually did get an answer to my e-mail today, FRI April 22-2011! Now, that you poked fun at me, I need respond likewise. :nutkick:
