We recently moved into a new home and the owner before left us a huge fish tank, it has a filter system we were not sure how to work. It stopped working and we had no idea what to do. We found Aquarius Aquarium and are so happy we did! The woman on the phone did all she could to trouble shoot over the phone so we didn't have to spend money on sending someone out. Unfortunately we couldn't figure it out and had them send someone. The guy that came out was so nice and very knowledgeable, he knew then problem right away and was able to fix it! Will use them again if needed and 100% recommend them.
