Does cleaning gravel kill good bacteria ?

my lfs guy told me to vac every 4 weeks when ya do a water chg, hes been in business 20 yrs so im going with that, what i would like to know is when u do a water chg/vac how many days do u wait to chg the cart. in a power filter i have a bio wheel peng, in a 20 gal long or should u replace cart prior to the vac/chgs? im planing on doing my 1st water chg this week end, i cycled my tank and its been running now with fish in it and cycled for almost 5 weeks, the lfs guy told me to wait 4-6 weeks b4 1st chg + vac + im doing just taht and all my fish are fine and tanks is always crystal clear..i had an amonia spike about 15 days aout lost a cpl fish then it was fine so aparently this method / time fram is working for me, but the cart time frame chg + vac is a question i would love to know, i forgot to ask my lfs......and always like the relaible info on here, i just have diff veiws on the time frame for a water chg but, hey it works for me.....love all the veiws on here plz advse, as always we reallllllly appreicate it were learning as well.thx!!!!

That's what counts ;) Teeny tanks (mine's at work) are much more work to keep stable. I'm looking SO forward to having a larger tank at home :wub:
