Our Calcium reactors are some of the finest available. Fabricated completely from cell cast acrylic, and utilizing high quality components throughout, we marry solid performance and a cost conscious design style to provide the best value possible for our customers. What some see as options we see as necessary to offer the best product available and our attention to detail is obvious in the finished product. We sink the tube into the base and flanges and utilize 2 part Weldon 40 to join it all together for nearly bullet proof joints. Each reactor is completely assembled and individually wet tested to ensure that there are no surprises when you set up the reactor. Below are some of the features you can expect from an Aquatic Systems Design calcium reactor.
