I brought two to try them out. They were 'ok' but nothing special, lets be
honest, we've all spent quite a few pennies keeping our salty fish friends
happy so I gave up on them and brought 2 extra powerheads to give an all
round better flow.

Captain Feedback, If you want my two old hydor flo wd's (found one of them)
send me an e-mail and you can have them/it.
