Reusing water??

[Twizted1]

I bought a cube for a qt tank yesterday. I was wondering if I should use some of my water from my dt to help give it a boost? Or should I just cycle it like normal? Or I was told I could use instant bacteria stuff an put fish right in? I am going to run it @ hypo & figured I could get a few of those little puffers to keep everything company that runs thru that tank. Any advise would be appreciated.

^this^ I also use "dirty" water from waterchanges on my coral/invert qt tank to do water changes on my other quarantine tanks. salt is cheap, but this way I can do waterchanges on my qt's that i otherwise probably wouldnt do.

ok thanks for the info. I figured there is some bio in the old tank water so why not use it.

I filled my QT from my DT I even stuck a filter cartrige in my sump for a a few weeks prior to add my bio. It worked fine for me, i even use my DT to top off my quarentine during water changes so I really only make enough water for my DT.

The only problem I see with using display tank water to fill a QT tank is that you'd want to leave the qt tank without fish for 6 weeks if you do this- you could have brought over pests from the main tank.

If the tank is just cycling, then that's probably not a big deal. But if it were for a fish you planned on getting in the next six weeks, I'd hold off.
