The used Tetra Whisper 3000 on the 55 gallon tank I purchased in December is not working correctly. Half of it is not filtering at all. The siphon tube broke a month ago......long story short - I'm getting a new filter. At the recommendation of the survey I am getting an Aquaclear 70. I have ordered it and it is on the way. Question - how do I change to the new filter without losing my cycled tank? Thanks for any suggestions you can send my way.

You can run both for about a week and move the filter media to the new filter or just move the filter media to the new filter when you start running it.

Very quick reply! Thanks - the new filter should be here by the end of the week - I'm going to do a water change and some vacuuming today to try to help keep things clean until full filtration is back. Fish seem to be healthy and happy.
