i just got a 20g tank running yesterday. I took enough gravel out of my 90g to put a decent layer on the bottom of the 20. The power filter thats on the 20 luckily will accept an emperor style filter pad. So, i take a filter out of one of my emperor 400s thats been running for like 6 months and and i know is wrapped up in bb and put in the 20g tanks filter. It seems to me like this would be ready to accept a Convict, and i have the perfect candidate on standby
. Any suggestions? As always, any help will be greatly appreciated.
