I want to know if I can empty all the water from the 29 including gravel, and plants, and both wisper back filters, will my fish be ok? Or do I have to cycle this tank before adding my fish into it ? I will be taking all the water from the 29 and adding it to the 55, and all the filter media and gravel, plants and decorations. I have a chance to buy a 55 gallon tank tomorrow with a stand for 75.00. If just changing over the tank water, and adding all the stuff and more water will be safe then Its a go, if not I will pass the tank to my mother. I want my fish safe !
