Well, I have been watching this forum for a while and now have an emergency to post!
I had a little cyano problem, so I bought some Chemiclean
Red Slime Remover and put it in Friday night around 8PM.
It says to change out the water (20%) in 48 hours. My 48 hours are up and I totally screwed myself (and probably my fish!) and hit the LFS 20 min after they closed.

So, I'm without water to change. I did wind up putting the carbon filter back in tonight, but that needs to be changed out too and was on my list to purchase tonight!
Will my fish be okay until tomorrow? I have one Leather Toad in there as well that seems to be pretty closed up right now and not sure if that will be affected as well.
I'm not sure what to do. I have an Oceanic Biocube (14 gal) if that helps at all. Everything has been running great and water levels have been dead on. I just had some
red slime activity as of late that I wanted to clean up. And now I do this. ARGH!
Thanks for your help!
