Your tank looks really nice! Not ghetto at all, I really like it! Have you thought of doing an Aqua Clear 70 or 110 refugium mod? You can run your chaeto in there and still have room for some chemical media and filter floss or polyfil. Something like that would be more suitable on your size/style of tank than mine!
Thanks for the kind words. that's an idea. One of those two filters would work. did you ever find a good algae?? There's a Facebook page I really like called "Saltwater Aquarium & Reef Keepers." People there are quick to respond and I've found some of them to be very knowledgable.
