Called him to help me with a failing aquarium, he corrected all my mistakes and explained to me everything in detail of how I was misled. Since then, he services my "Now upgraded" (2) saltwater and one freshwater aquariums monthly. All I have to do is "feed the fish", he does the rest! Which by-the-way is his motto. I have also recommended him to 3 friends and business partners of mine and they love him too! This guy is the best!!
