Moving to a new tank

[cmb1177]

Hi everyone; I'm going to be moving some fish from a 22 gal to a 30. I have only one filter that is going to move, too, and I'm wondering what is the best way to make the move and keep the water quality as high as I can. So, far I'm guessing I should siphon water from the old tank to the new, feed very lightly, and test the water daily for spikes. Does anybody have any further advice? Thanks!

Forget the water it has little if any good bacteria in it. Move the filter, move the fish, maybe a decoration or two. Check on you parameters daily but you should have little or no cycle.

Agreed with rich, I would just keep half of the water for its not a shock to the fish. Be ready for a waterchange.

Agree with both above. I would move some of the water to keep from shocking the fish too much. Think of it like a big water change.

While its true that the water column does not house your bacteria, it does have its purpose in changeover. The water is already the right PH and temperature, and can have other nutrients. Adding half new water and half old water will prevent shocking your fish.

Same water, same house why move dirty water.

I would just keep about 25% of the old tank water to make it less stressful on the fish

I would personally go 50/50 with the new tank. I can't remember where the link is but I read about osmotic stress. The water in your old tank is stable and the fish are use to it. Just my opinion.
