Picked the tank up yesterday and will start working on it in the next week. Planning for a mixed reef. I ordered it with an external overflow assuming it would be like a previous P.A. tank I had. They're no longer making the old version which was a glass box siliconed to the back of the tank which housed the drains and return. There was a small rectangle cut out of the back glass for the weir. Now they're using what they call their Tideline overflow...which is basically a ghost overflow and a return in each corner of the back glass. This will be a first for me to plumb this kind of set up. Equipment list so far: Tank: Planet Aquarium 130g Crystaline tank 60"x24"x21" Return: Reef Octopus Varios 6 Sump: Trigger Sapphire 39 Lights: Aquatic Life T5 Hybrid with a couple XR15 and an XR30 Skimmer: Either the Vertex Omega 180i or SCA 302 (gotta see which will fit best) Powerheads: 3 Neptune WAVs Controller: New Apex Dosing: Apex DOS ATO: Tunze 3155 Will be using Argonite special grade sand and a mix of reef saver rock and pukani. A vendor here on R2R advertised he had a bunch of live rock that he had ordered for a customers build over a year ago which had just been sitting in a tank. He was selling for $1 / lb plus shipping. It looks like most of it is pukani and included some nice pieces...like a huge branching piece. I got 100 lbs.
