Restarted Fish Tank Thoughts And Ideas.

I can only see what looks to be either a U3 or U4 filter in there. Would recommend running an external if your not already, holds much more media and will handle the bioload better than the U4.

Nothing wrong with U4s however, i have a U2 running permanently in the 75gal for use in the QT/Hospital tank.

yeh that is a u4 filter, i was wondering, should i add more media becuase the u4 doesnt come with much.
