  • review rating 5  I don't usually leave reviews, but in this case I'd be doing a misfortune to everyone that hasn't gone to this shop. Anyone that doesn't give a five star rating to OSA doesn't know what they're talking about. It's easily the best Aquatics shop in New England! Thank you to Scott and all the wonderful staff for making our experience an amazing one.

  • review rating 5  Thrse guys are great! I just started out keeping coral and fish and Chris and Scott have been a wealth of information they are willing to share with anyone. Never pushy with sales, happy to recommend other stores, and genuinely excited to see when your tank is doing well

  • review rating 5  Very knowledgeable! Been to the store several times and built an amazing community tank from here. Called on several occasions with urgent matters and the staff is always ready to help over the phone. I live in the other side of the state but would rather spend my money here than anywhere else!

    thumb Christia Pirdinock
  • review rating 5  Had a complete disaster with my 220. Bottom blew out and tank was quickly draining. I left a frantic message for Scott, got an immediate call back, and he quickly responded with a crew. They quickly and calmly managed a reefers worst nightmare. Seriously folks...Scott and his team are the best. I buy my corals and supplies from them, they completely replumbed my system and added a mixing station, and now showed how they handle a major reefing emergency with speed and professionalism. No better company in this industry then OSA.
