Well without starting the "best filter debate" I will just say this.
I personally am partial to using a wet/dry trickle filter for FO tanks.
You have some LR which is great, a little more would not hurt.
As long as your method or equipment is providing adequate bilogical, mechanical and chemical filtration, then you'll be successful.
A living sandbed, live rock and actually every surface in the tank can provide sufficient bilogical filtration. A good protein skimmer will aid the biological filtration as well, plus remove nasty organic compounds. A small hang on power filter can accomplish this as well, plus allow some mechanical filtering for small particles. Carbon pads can be used with these filters as well.
After all that is said .... I like wet/drys because:
1) you can add/remove biomedia as necessary
2) overflows do a great job at suface skimming
3) carbon can be added to the wet/dry in various amounts
4) wet/dry sumps provide a great place to put your heater, protein skimmer, do water changes and add trace elements.
5) normally you will get higher water turn over in the tank with this set up.
Thats just my opinion - for what it's worth.
Good luck
Brian
