I have a 29 gallon tank now and run the following:
-AquaC Remora Skimmer with Maxijet 1200
-AquaClear 110 modded fuge (
Kraylen's Aquaclear 110 Fuge Mod - Nano-Reef.com Forums)
-30 lbs. live rock and about 1" live sand.
-2 Hydor Koralia #2's for flow
You will be able to add a sponge filter to the AQ 110 fuge when you need to polish the water. I usually put one in for about 12 hours after water changes to pick out floating debris. If you leave it in too long it will start to produce high levels of Nitrates. The Fuge also gives you a place to run Chemipure or any other media you would like.
I am pretty happy with the setup. 1 year in (knock on wood) no water chemistry issues. I would also invest in an RO/DI unit or at least make sure you have a supply. Otherwise you are looking for algae issues.
I like the size of the 29. I think you will be happy with it.
