Well, I decided to jump in with both feet. I'm building a 180 gallon tank with a IceCap 36 sump. Here is the initial setup with Apex Controller, UV Sterilizer, Vortec M return pump, Tunz ATO. I just filled it with RO/DI water Yesterday- had a few leaks to plug, but it stayed dry overnight, so I added salt today (Red Sea Black label). I have a Seneye monitor that I plan to use for NH3 monitoring during the initial cycle and to help check PAR values as I set up the lights and position coral. I have a Reef Octopus skimmer which will go in the sump as well.
