That was 2 months ago and now the new tank is up and running and there are 7 Tiger Barbs in there to do the cycling while the bigger fish wait their turn to get in.</P><P>I'm using a standard wet-dry filter. About how often do these need to be cleaned? I know the bioballs never have to be cleaned but I'm assuming the filter material above should last about a month or so?</P><P>After the tank has been cycled, is it advisable to put carbon filtration in the filter?</P><P>What kind of chemicals/vitamins should I stay away from to avoid yellowing or discoloring the tank?</P><P>What kind of auto feeder can I use in this tank? It has a removable insert in the top of the acrylic. Most seem to be the type to hang on the back of a tank.</P><P>The prefilter overflow sounded like a toilet constantly flushing, I filled the prefilter with bioballs and put filter material at the top to filter out any food particles to act as a silencer. Is this OK? Can anyone recommend another, maybe better, way of silencing the pre filter?</P><P>Thanks for your help, I'm sure I'll have more questions!</P><P><BR>EdMon, 09 Jun 2008 09:32:43 GMTecarfar
