The question is, on a 46 gallon bowfront already set up with a emperor 400, mind you there is a couple cichlids already in and tank is balanced and clear.

If you wanted to add more power, what would you do?

bottle of prime 8.5 oz, an aquaclear 100, free shipping for $64.06

or

filstar xp2 for $93.49 free shipping

I have other tanks which use the aquaclear and there great filters, along I use th rena filstars as well both are good, cant decide?

I would spend another $30 and get an xP3….

You never know when you might upgrade to a bigger tank...

Well, you need the Prime either way right?
I'd say that an Emp 400 is enough filtration for a 46 gallon tank. If anything, maybe add a powerhead to agitate the surface more and/or kick up debris into the EMP's intake. If you want a bit more mechanical filtration for clearer water, get an aquaclear powerhead and add the "quick filter".

goto dr. foster's and smith and get the ac110 for $44.99, if you really want another filter, or just get a powerhead

I say do this...http://www.cichlid-forum.com/articles/power_filter_tricks_v.php and add a USJ/UGJ. I never used the USJ or UGJ I only just heard of them ( I guess I was living under rocks ) but they make sense. The 400 is allready a great filter IMO and to upgrade from that I would just get a canister.

8) Since you already have a decent HOB filter I'd say add the 'Can'. "T"
