You can also see from the pic above, that I went with the Synergy Reef Shadow overflow. Had to drill a couple extra holes in the tank, but it's a nice unit. Still to do...paint the back of the tank black to hide the pluming and wires and give it a nice clean look.As for the holes in the bottom...they tank was previously a freshwater tank with a UG filter. As the holes are already there, and I like a nice clean look in the tank, I will be re purposing them for a closed loop.Thus far, I have a few things ordered, including a Waveline DC6000 and a Waterblaster HY7000. I'm not yet sure which will be the return pump vs the closed loop pump, but I got great deals on both, and I guess I've got a little time to figure it out, as I'm still working on modifying and refinishing the stand.PUMPS:Return vs Closed LoopWaveline DC6000 (1585 gph)WaterBlaster HY7000 (1800 gph)Heater:Cobalt 150w Neo-ThermEheim Jager 150w (Back-up and extra umph for those cold Northwest months)RO/DI:BRS 75GPD 4 stage value RO/DIRock & Sand:50lbs Marco Rock along with a few seed rocks I'll pick up locally60lbs Carib Sea Arag-AliveSalt:HW-MarineMix Reefer Salt - I've always run Reef Crystals in the past, but decided to try something a little different this go roundLights:As for lights, I'm holding my breath a bit. I found a too good to be true deal on eBay on a pair of these:Vervve Plus LED Fixture with Bluetooth - GiesemannBeing the deal that it is, and being that I have to wait an extensive time for economy shipping from China, I will believe it when they are actually in hand...Should this not pan out, lighting is up in the air, but will either be T5, LED, or a combination of the 2 depending on the deal that I can find...Skimmer:Yet to be determined. Depends on the deal, though I am looking at the Simplicity 120DC or 240DC. I am vertically challenged in my stand. I cut the bottom out of the stand which gives me 26", but will need room for plumbing and I don't think the 23"-24" skimmers that I like will be fun to maintain...Controller:As this was a bit of a budget build, I wasn't going to add a controller, or if I did, I was just going to pick up an AC jr or Reef Keeper lite, but I came across another deal and will be picking up an Apex with a pair of EB8'sSump:As for a sump, I can't justify getting what I want, which would need to be a custom job to work in my stand. So I'll be using a pair of plain 15 or 20g tanks plumbed together, with the left being the "system" sump, and the right being a fuge.I think that covers the basics up to this point...I'll post up more as I go. Happy reefing all.
