I keep a bunch of rubble, biomedia and rocks in my 130G system sump and another wet storage area with flow that my system has. I need to fire up a Nuvo20 AIO I have in storage and use it temporarily as a frag tank for about 6-8 weeks (waiting on a customer frag from GCs). Now, this display that has all this rich media in it (I should be able to do an instatank with it, I think) is on day 14 of a flucanazole treatment. I really wanted to try and go another 3-5 days before I start with large water changes. Do I need to worry that the rubble/media would come out of the tank at this point? I would use fresh salt water and not water from the display. Since I will only be doing this temporarily, I won't be putting fish in the temporary tank. My main display has a very light bioload, fyi. Thoughts?
