I am picking up a 125 gallon freshwater tank this weekend which currently is running 2 aquaclear 110s. my question is will that be enough from my 2 oscars and 2 Jds. I know they are messy and I have been looking at the rena xp4. does anyone have any experience with the rena filters? or any reccomendations? what is everyone using on their 100+ gallon tanks?
