I have a tank already(see my profile), but have brought my girlfriend a Eheim 14 us gallon kit. It has fitted light, a Jager heater and an Eheim internal filter. We will set it up next weekend after getting some more sand, wood etc. I have put the sponge for the filter in my tank to start it off, held under the water with a sucker. I was thinking if we use the old water from my tank to fill 75 to 80% of the new tank, plus the sponge that will be a week old, how would this work out? Will it still need cycling, finish off cycling, or would be able to support a couple of fish? I'm quite happy to wait, it's just that I was wondering.
