Want to upgrade filter

[reeftankman]

I have an inexpensive foam/bio-bag filter and a protein skimmer on my 37 gallon reef tank, and I would like to get a better filter...any suggestions...?

Aquaclears are great filters. An AC 500/110 would be perfect for your tank. It gives you lots of flow, and plenty of room for media in it's compartment. You can even build a small refugium in the back!
