Dave helped us out of a bad situation.  He responded promptly to an emergency call when our 72 gal bow front frame decided to split.  He set-up our new 150 gal freshwater tank and both the fish and I couldn't be happier.  
He was prompt, conscientious, knowledgeable and fantastic to work with.  
I am a tough consumer and you can't get better than this.

Couldn't have asked for anything better.  Great price, good knowledge, well prepared, cleaned up after themselves.  Really worth it for anyone who doesn't want to maintain their own tank or anyone who just wants to watch and learn from a pro to get setup.  Dave was happy to help every step of the way.

Dave and his assistant were prompt, professional, friendly and very reasonably priced. Dave understands the beautiful world of aquatics. He has practical tank, and mechanical set-up knowledge, and he stages visually dynamic, stunning aquarium environments. Most importantly he loves fish and creates a tank world that fosters their ultimate health, happiness, and well being. Thank you Dave and Marine Concepts!

I don't frequently post reviews; but this guy totally deserves a great one! I contacted Dave for a one time cleaning bc I was very pregnant & too big to properly clean my 90gal tank. needless to say that was a year ago.. Dave is very professional & does a great job.. my community tank continues to appreciate his business.
