One of the pics in a previous post shows a ton of fittings and valves. Most of them will be used. I plan to build a manifold off of the return to allow me to easily add reactors for carbon, gfo, and or bio pellets. It will also have a valve for quick and easy water changes between tank cleanings. It will make more sense as it comes together.
Yes, I will have a sump. I'm using a glass holes overflow but plan to plumb it in like a herbie. GH says not to valve their product because it will make it noisy but I bought the 1500 gph kit because it has (2) 1-1/2" drains. This way, I can valve each one and dial in the appropriate display water level as well as split the drain so I can feed the fuge directly from the display. I'm using a mag 9.5 for the return so I expect that I'll be running about 800 gph given the head. As stated earlier, I'm going to run a manifold off the return......I'm going to Tee off the return and reduce to 1/2" pipe with 3 other tees that will feed reactors. One for carbon, one for GFO, and a future one for biopellets if I decide to go that route. I'll also have a valved drain that will allow for quick water changes. While it seems like a lot, it will allow me some flexibility that would be difficult to add later vs. putting it all in now while everything is still dry.
No worries though Russ....I think you're going to beat me to the finish on this one. I still have lots to do on the stand before I can even do a leak test. Plus, I have a crazy week at work this week and will get nothing done on the tank so tomorrow is my last day to get anything done. Hopefully I can build (dry fit only) the manifold tomorrow and basically "rough" in the plumbing. I'm not going to glue anything until I'm confident all fits properly. Then I can glue and leak test.
That's a pretty good order of things. A few details I would suggest...
Be sure the new SW is the dame temp and salinity.
Use all of the old substrate if you want to. Why limit the bacteria your adding to a single cup? The more bacteria you add the less change you'll have of seeing a cycle. The tank may be cloudy when you switch but there should be no harm using it.

You should see 100% survival.

Definitely will be sure the new SW matches temp and salinity of the current tank.
I was concerned about using all of the old substrate because in removing it I would stir up a bunch of detritus and any nitrates trapped in the bed. That's one of the biggest concerns I had really.
im gonna have to tell ya with what your thinking, dont use old substrate, it just isn't worth it. i would get new sand and just use a cup or two to seed the new sand. i've seen plenty of threads on RC saying just skip using the old stuff and get a bag or two of new sand. also, dont fall for the "live sand" crap thats like 40$ a bag, its not live by the time it gets to you lol.
My tank has substrate that is 15+ years old. And when you saw in my 75 the other week it had recently been transferred from the old 50. I didn't test to see if there was any kind of cycle but I had zero issues with the livestock during or after the upgrade.
Interesting that both you and Tom have total opposite positions on this. I'm inclined to go new if I decide to use a substrate. Reason being is that it's kind of like a fresh start to the display. I'll do some searching on RC as well.
I too used all my substrate ( 2+yrs old) from my old tank for my new tank. Added all new dry Pukani and 1 rock from old tank. Never had an issue. Don't believe I even had a cycle
