Hmm well i just had a thought but dunno if it would work or if the fish place would do it. But anyways,Kim said i should cycle my 2.5 with my current filter then once its all done,put it in the 5 and good to go. Well I might still do that,but just wondering if its possible to put my filter on someone elses tank (with healthy fish and cycled obviously) let it hang out in there for i dunno quite awhile for it to cycle and then put it on mine? I would ask my sister and put it on hers but well...she doesnt take good care of her fish so I dont think i wanna do that. At least at the fish place they test their waters every day. Just a thought. How long is too long for the filter to be outta water till it gets to its new tank? Else can i get some filter media (that would fit in mine) and do something that way? Or is that still cycling with a fish lol. I dont wanna do anything that could potentially kill my fishy. So if anyone can help thatd be great. Sorry for all the posts and questions. I just wanna do whats best for my fish. Thanks alot!!!
