I have a heavy planted 29 gallon tank with a ton of fish. I am moving them soon to a 55 then keeping the neons in the tank with a few corey's. 

I am running a fluval 305 on the 29 with a hang-on the back filter that is doing 200 gph. With this in mind I am going to use the fluval on my 55 and then possibly add another filter on my 29 that does a 100gph. So I will turn my tank over 10 times a hour in water volume. Would that be good or bad idea?

55 gallon tank I am doing a big school of congo tetras. I have 11 of them and I was going to use 2 power heads that will alter flow when one is on the other one will turn off and so on. Which the power heads do 750 gph a piece. With the fluval doing 260 gph. My 55 will be heavy planted as well. 

If you have any advice I will appreciate it.
