I have a chore for myself and hubby tonight..I sold one of my 55g tanks so when it leaves my house I need to move Jasmine and them in their tank to the spot where the old 55 sat. I plan on not scrubbing glass or messing with the filters..just simply taking out water and quickly moving tank. so, can I take out 100% of the water and refill then just turn on my filters and be done?...The tank is barebottom except for some large river rock on bottom.. I just want their tank in place off the old one..which is on the other side of my love seat I have 2 huge penguin bio-wheels and 1 extra filter that sits inside the tank..all filters are nice and full of plenty bacteria.. just need to move their tank..

Yeah that sounds like a good plan. I may even leave a few inches of water in it.

So, no need to worry about losing cycle?

I bought a used 50 gallon from a Koko member. She gave me about 12 gallons of the old tank water. I made the 20 minute drive from her house to mine. I used the old filter with the bio medias, used the 12 gallons and filled the rest of the tank with aged tap water, put my new adopted fish in it and I waited. Everything was at 0. Will the ammo appear or will the nitrates appear? Well the ammo appeared and the cycle was lost. I waited a couple of days and then dumped the noodles from my established 20 gallons into the filter. This kicked it into overdrive instantly and the tank cycled overnight. It cycled so fast that I never even saw Nitrites!

If you are moving the tank within the house and you are saving all the water and the filter and the bio media has no time to dry up, I don't see how you could possibly lose the cycle.

As Jack mentioned, it's important to make sure your biomedia doesn't get dried out. Keep them in a container full of aquarium water, move your stuff, and you should be fine.

Just keep an eye on your parameters to make sure no spikes have occurred in the process.
