A dip into the local knowledge pool

[Pier Pressure]

Very welcome, Howdy20012002.

I am not sure if this is the same concept but we over-filtered our 150 gallon freshwater tank with two Rena XP3's and one of those new Fluval F4s or whatever they are called. We have a fairly large bioload and are still doing the water changes once a week, the concept being why take a chance?

Who wants to watch their livestock go south if the concept is wrong? We just decided we did not want to take the chance, especially on that size of tank.
