i bought a protein skimmer on tuesday its the tunze nano skimmer 9002(its internal)
i only got time to set it up today and i followed the instructions pluged it in and it looked fine from the top i then looked into the tank where i saw millions of litte bubles pouring out of the bottom!!!is this supposed to happen?

another q, my to common clowns have started kinda fighting a little bit over the last few weeks but tonight i noticed the fought a bit and then the female started to twitch.....any ideas???
thanks

not familiar with internal skimmers but you will get some bubbles from most skimmers.
re your clowns: if they are juviniles then they will squabble until one asserts itself as the dominant one. then it will become the female and you will have a pair! read up on clownfish, the sex change is pretty amazing.

Not an expert on skimmers as I only have one about 2 months but I had loads of tiny bubbles in mine for about 2 weeks and then it cleared.

I get the impression it will be bubbly until all the water is skimmed and when it settles down you will find that it will start up again every time you do a water change but then only for about 6 to 12 hours.

thanks for the help
