D-D Reef Pro 1500 aquarium and installing Calcium reactor | D-D The Aquarium Solution
Question: 

Can you fit a calcium reactor in your 1500 reef tank

Answer: 
Dear Andrew
 
You can install the Calcium reactor either by sitting it in the sump or housing it in the cupboard next to the sump. The shelf can be removed as required and the internal head room is 429mm
 
 
I hope this helps Tony
