I just purchased 3 360we soo far sps love them.
The thing with Kessils is they look way dimmer to eye than they are ..
See what area a 160we covers and if the frags are in that Area then you should be fine.
And yes 360 is lot more powerful than 160 but it's good enough..
Also I have observed that par readings never come out right with Kessils.
So keeping the A160WE for my frag tank is ok you think?
