Need to know something about filtration on a fish tank?

i'm gonna be getting a second 30 gallon tank tomorrow basically i have cichlids mixed with other fish in a tank right now i'm gonna set the tank up for 24 hrs and let it cycle but i'm thinking about using the 2 aquaclear 30 gallon filters from the one thats running already and put that on the new tank with the normal community fish basically a betta and some bala sharks and 4 cory cats. from there i'm gonna take the 2 aquenon filters i will have that are also 30 gallon filters and put that on the cichlid tank this tank also has a 20 gallon power head and a 30 gallon tetra under gravel filter that the power head is hooked up to as well as it has a bubbler at the other end powering the other tube 2, will it be ok to put the new filters on the existing tank without having to worry about the tank recycling and how long will the other tank take to cycle if i put the other 2 filters from the existing tank and put it on the new tank.
