Thanks everyone, for all the help. I think I have my situation figured out
now. I am going to buy a foam insert definitely but I'm not overly worried
about it any more. Quick update on my tank, I came home from work yesterday
(where this forum has been seriously impacting my productivity by the
way...) and found one of my goldfish floating. I suppose in the long run
it's a good thing, now there is just the fantail and one plain goldfish left
so that might be an easier load for the new environment to handle. I
changed about 25% water again last night and my ammonnia level is down
again. I'll test again on Friday or Saturday and I'm hoping it will start
going down on its own and if so I'll cross my fingers for a nitrite reading.

Cheers

If I understand it right, the filter came with a mesh bag - not a
bio-bag, or foam insert. Without enough bio-media, I can see a filter
that may not be able to keep up with the fish load - if that's the
case, a little foam would indeed be "magic" ;-) ............... Frank

Hmm... I thought the original post said Whisper Bio-bag.


The model that came with my Tetra All-Glass Starter Aquarium kit does
have a "Bio-bag", consisting of an "Aerobic Frame", a mesh filter bag
that slips over it, and "Whisper filter carbon" inside the bag. The
instructions say that the aerobic frame is "deeply etched so as to
provide a receptive surface for aerobic bacteria." I suppose when you
need to chnage the bag you keep that colonized frame.

You guys doubtless know this routine/functionality. Just clarifying my
model.

Cheers,

Fred
