Turnover rate too high?

[Cecropia]

I was given a used xp2 today and free'd up a marineland bio-wheel 350. Wondering if I should put it on my 25 gallon pike tank (running an marineland bio-wheel 150 and a freebie aquatech 5-15) or my 20L wolf tank (currently running a marineland biowheel 150).

It'd put either tank at over 14 as far as turnover rate goes. You think that'd be too much?

mine is over 16

should be fine unless the fish is struggling to swim.

Added it to the pike's grow out a few mins ago. Not near as turbulent as I thought it was going to be.
