FX5 newbie help

[wonword]

Hello,
I bought my first FX5 used. It is in perfect condition, very clean and only 4 months old. Anyway, I first started it up and it sounded good, the sound of air every once and awhile. But I noticed that the tubes were on the wrong nozzles, so I switched them. Now I'm getting the sound of air inside the filter. What is the most common cause of this. Also, how do I lower the water inside so I can take the top of to look at it?
Thanks,
John

Have you turned your filter off and see if it will back siphon and fill its all the way up?
On the back of the filter, next to the pump, you should see a little valve with a nipple sticking out. It is so you can stick a hose on it a drain the filter.

Mine took a few hours to completly get all the small bubbles out of the bio max rings.

to look in it just turn the hoses off, remove and take it to the sink.

John, just let it run. The filter will work the air out of it. Here is a link to the manual (about half way down). http://www.hagen.com/uk/aquatic/manual.cfm
