Hmmm...I might have an idea. By the end of this week I will have a new filter, a Millenium 3000 (trading it in because whisper is too noisy), which is the same filter I have on my 50 gallon goldfish tank. What if I were to do a switch? Take the Millenium off the goldfish tank, put it on the 55 gallon. Put the new Millenium on the goldfish tank. Start off with a handful of fish in the 55 gallon, then every week or two slowly add fish. The only problem I see with this...would I loose the cycle in the goldfish tank? If this would be a problem, then I could take the filter media from the whisper and stuff it into the new millenium filter. But would there even be any bacteria on the filter media from the whisper? Ok, if I've got anybody confused, this is what each tank would have:
55 gallon- cycled millenium from 50 gallon
50 gallon- new millenium with filter media from whisper
The reason I would do this is because I am going away in 2 1/2 weeks, and do not want to ask my dad to do yet another thing for me (he would have to be adding ammonia), as he is already taking care of all my fish, my 8 birds, my dog AND my cats. I also have 5 yo-yo loaches stuffed in a 5.5 gallon, and I don't know how they would do without a water change for 10 days, as I am doing water changes every 3 days to keep the ammonia down. So that would be an extra bonus if I could move them before I leave.
