Oh, right. I do not like the sound of clogging.

Suppose I got another external filter, I think the one I aquired is a bit big, I could just buy some tall fake plants and attach it to the tube?

With the end of the tubes though, where do they need to sit? I mean, do they need a space around them, or a cartain height from the gravel or what? I've never seen one in use.
I suppose an external might be ok.. assuming you have to have the filter lower than the tank I could hide it between the unit my tank is on and the sofa. As long as it was a quiet one!

Oh and do you get quiet air pumps? I remember I had one once and I had to selotape it to a sponge because it kept vibrating off the table! It's just my small filter is there because it has an air inlet and my oh hates it because there is condensation in the pipe so its noisy.

Sorry for all the questions!
