Eric Armstrong, Carlsbad

“Been in the hobby off and on for 30 years. Steve has taken a good retail / service shop and brought it to the next level. If you care about the health and environment your reef aquarium provides to the many animals we enjoy in the hobby, I can think of no one better suited to help maintain these delicate environments than Steve and his crew at Aquatica."
