I got my first AI product in the form of an AI Nero 3 for my 37g display. Wow. The program is intuitive, and makes it extremely easy to monitor the action in the tank all day. I liked the programming, and quality of the product so much that I decided to put in an order for two AI Prime 16hd's the next day, before ever actually using the products (Based off of testimony from other reefers). Needless to say I am beyond excited to use AI's on my waterbox reef 180 project coming up in spring. I plan on using AI components, being 3 hydra 32hd's (or two 64hd's), and 3 AI Nero 5's. Anyone have the same awesome experience with AI products? Also, any suggestions for return pumps? Should I set up an Apex system with the return pump, trident, dosing pumps, and other Neptune apex controlled goodies? Would live to see/hear what my fellow reefers are using for "smart" equipment in their systems! Need some ideas.
