Ca Rxr Rec. for 120g+40g

[SuperDragon]

Hi, I'm shopping for a new Ca Rxr for my 120g+40g
I've used a Geo 6x12 before and it seems not enough for my 60g cube under lots of sps.
I was just wondering if I should got to a Geo 6x18 + second chamber for my 120g or a Vertex RX-C 6D dual (like on BRS videos). The vertex website dosn't work correctly and I not sure about their support.
Any advice or other brand ideas would be great.

thanks

Rich

vertex makes really good products, I have seen a lot of their stuff in person, very well made and thought out

Love my Rx-C 6D. Had it for a couple years now on a 120g sps dominated tank with great results.
