Well just got back from my lfs and now have a cpr bak pak filter/skimmer. They also talked me into buying 3 damsels....They said they were needed to speed the cycle process up a bit. You need fish pooh to create the ammonia. Live and learn I guess. I am still in the need of liverock. I was going to wait until some becomes available on here somewhat close but I was surfing around a bit and noticed on ebay you can get lr for 2.19 a lb and 27$ to ship. Anyone have any input on lr bought online? I can get all I need for just under 100. Not too bad....
