I used a AquaClear 30 on mine which is in the process of being upgraded to an SPS nano tank after spending 17 months as a Soft/LPS coral tank. Note...this tank had no fish in it, strickly corals and CUC only, other than a Waratah Anemome.
Aquarium Filters: Hagen AquaClear Powerfilters
Here are a few pics of it about 6-8 months into the project...
Full Tank Shot, not the best but due to the lenses I have and its location in my home this was about the best in focus shot I could get
Here is the shot of the Waratah Anemone shortly after feeding it a morsle of cut shrimp.
This is a shot of the front right corner with a Kenya Tree coral that survived a move from Japan, there is also a cluster of Mini Feather Dusters I robbed from one of my sumps and a Elephant Ear Mushroom thats metallic Green.
Although it wasnt a jaw dropping tank at this point, It was a pretty easy to replicate tank thats a good launching point for jumping into SW. You just gotta pay attention to detail, keep things on a short leash maintenance wise and water parameter wise. This can sometimes be a bit challenging for the novice just cutting their teeth on a SW tank with a tank as small as this 10 gallon. If you want fish I would suggest something larger to start with though, cuase with a 10 gallon tank you will be very limited on what fish you can put in it.
