Upgrading from 72g to a 120g. More 6055s?

[MJAnderson]

Roger,

I have 2 6055s on my 72 bowfront. Upgrading to a standard 4x2x2 tank and keeping SPS (but I like sand, so no BB). Wondering if the 2 6055s + 2 always-on 6045s would suffice or would that totally screw up the Interval 2 settings? The 2 6055s alone don't seem like enough.

That should be fine, you could also add a wavebox or another 6055.
