Random Thoughts

Finally decided on my dream setup, so I went ahead and ordered an Elos 70 system. In a month or so I'll have all the parts delivered and ready to get wet, but in the meantime here's a product list.

Hardware

• Elos 70 system
• Icecap 250w pendant/ballast + 14k Phoenix bulb
• Vortech mp40ES
• Spectrapure RO/DI (sorry Melev, saved on shipping!)
• 50lbs. of 'reef saver' rock from BRS
• x2 American DJ 4-plug strips
• Azoo quad fan

My logic

• As this will be a species
