Fluval 405 on 11.5g Nano - Too Much?

[NanoReefer]

I'm running a Fluval 405 on my 11.5 nano tank right now.. currently only has a clown fish, red star fish, rock/sand.. I'm using it as a mechanical filter and for water circulation to cut out any powerheads/koralias.. however, I feel like it may be too much. nothing I see wrong with it but I don't know what my clown fish might be going through.

he seems to be happy with the current, I don't have sand flying around or anything. I know I can adjust it too but lately I've just had it on full power with no issues.. I'm curious tho what you guys think..

- should I cut the power down and add a koralia or something?
- Is it a bad idea to just use this for circulation?

I took a couple years off the hobby so I'm a little rusty.. any input would be great.

What media are you running in it?

If you have it wide open and its not clouding the water blowing sand around I would assume its fine. Also depends on what type, if any, of coral you plan to keep. If you clown looks like its struggling turn it down a bit.

Sorry never ran one of these on a reef but hope that helps some. Had a 406 on a 70 gal FW planted tank and that sucker blew things around like crazy.
