Lighting:
I'm using Lumenarc Mini Reflectors with AB 10K 250w MH's, and 2 110w VHO Super Actinics for supplementation.
Flow:
I'm using a single Reeflo Dart to supply my flow threw two manifolds on top of the tank. I wanted to go powerhead less on this setup. I think it looks great and has really good flow. The pump also feeds a small refugium that's attached to the sump. I have it plumbed now to also run my chiller, however I'm hoping to not have to do that. However my temp is getting pretty hot during the day!
I added ball valves onto the ends of the drain lines, this enabled me to quite down the sump by matching the flow to the pump.
Sump:
I don't like the design of my sump at all. It places the drains too close to the intake box for my pump, which is causing some slight micro bubbles to enter the main tank. I'm playing around with various socks/sponges/filter pads, etc... to see if I can cut the bubbles down even more.
