Skimmer for 40B with 20L sump

[uf_gators]

The cs1 by seaside aquatics is the same as a bubble mag NAC7 but with the better pump... I love mine In my 40 breeder w/ 20long sump...

I've been using a reef octopus nwb150 on the same set up and I haven't been able to get it to skim well. It is too big and will only skim very wet consistently.

I'm in the process of exchanging it for a nwb110, or maybe a bubble magus nac3+. I haven't decided which one yet.
