So I've been in the hobby for almost ten years 3 doing coral and now 2 professionally . I am an aquairim service tech. And sales at at a small mom and pop store. But song be fooled. We are good. The big name store call us in to fix their filtration as well. I have a 110 gal mixed reef with 20 gal refigium and a 24 gal nano with 10 gal custom made refigium. Have lots of pictures and information to share. And hope to learn alot more by being part if this site.
