i have recently come into possession of (2) mp10's and (1) mp40. my tank is a 125g (72x18x22?) i have a ton of rock. what i'd like some feed back on is.... i'm ditching my 7 y.o. koralias (a 3 and a 4) i always thought my tank lacked for flow. do people that own the vortecs or know alot about them think it would be best to use the 3 i have, or sell one of the mp10's and use 2 mp40's and one mp10, or sell the mp40 and use (4) mp10's? i hope this makes sense... whatever i'm gonna do, i wanna do it soon. any feed back would be appreciated.
