Whisper/Emperor/Penguin Filter Users

I like that the Imagine filter frames have a thin biofilter sponge. I also rarely run carbon unless necessary...the Imagine filters are WAY cheaper than stock for when you DO need carbon...and IMHO way better too; really cheap in the 12 or 24 packs...

yuppp the other day i bought just a single bio bag and it cost me $3+change so ordering a 12+ pack is definitely wayyy cheaper

im using carbon right now because my driftwood is still giving off tannis.. (though i still want to try purigen and see how it clears up my water)
