Mike, how do you mean? A hole in the 300g rubbermaid for the return pump..no I have not. Deciding if I want to build in an overflow box or how I wanted that to look. Did you have some suggestions?
Tank will be drilled at Reef Creations tomorrow and drilled this weekend, decided on the Barracuda for the return pump and the dart for the closed loop along with an ocean motion 4-way...not sure when they will arrive yet. I am just going to build basically a stand connector between the stand and canopy on the sides to hide the lines coming to/from the aquarium. This will take care of the additional 8 inches of hole in the wall I needed to fill

Centrifugal pumps like the barracuda have one big downside, they cannot create much negative pressure suction on the inlet side of the pump. This means that if the pump is forced to create a significant negative pressure (even a few inches worth of water) the output pressure and therefore flowrate will be significantly lower. The specific model of centrifugal pump matters not, fluid dynamics hampers the design of any/all centrifugal pumps this way.
For example, a Barracuda may be able to generate 18' (432") of positive pressure; if memory serves they can only generate around 1' (12") of negative pressure before they cavitate (produce bubbles), and 4' (24") of negative pressure before they shutoff. I might be mistaken on those values, but the idea is simple, you can have very little negative head on these pumps before they start encountering significant operating problems.
This means the pump cannot be situated significantly above the water level of the tank upon which they're drawing from. Furthermore, they need large inlet pipes to draw off of. A Barracuda works best if it can draw directly off a 2" bulkhead fiting in the side of the sump tank. If that's not possible, at least use a 1.5" and prefferably a straight, short run. Trying to supply it on another tank with an overflow box is an exceptionally bad idea. These things suck a LOT of water, more than most overflow boxes can supply.
Unfortunately you allready have a lot of water in the sump which makes drilling the bottom side of it for a bulkhead (ideal) very difficult. Perhaps consider dropping a big magdrive in the bucket and pumping water temporarily into the display tank while you drill the sump tank and install the bulkhead/pump. Your only other real options for this would be to suspend the pump just above the water level (which could be disastrous if it ever falls in), or to use 2" spa flex, start a siphon, and pray the siphon never breaks (again not something I'd be comfortable with)

I dont have a dart for sale, but I'm pretty sure Randy has an extra he may sell you. I think he also has a barricuda but I may be mistaken.
I think you might be thinking of when I was talking about my dart taking a sh*t. Anyway, my new one came in today hopefully will be plumbed by saturday.

Thanks Mike, yes the water that is currently in the sump will be pumped into the display tank eventually and then a three day process of again refilling the sump with the RO/DI water. Need to get a container for auto top off storage, have not done that yet but could be filling it now while waiting for the display to be ready for water.

The tank made it to Reef Creations, meet up with Randy, Chris, and Keith there today to determine where the closed loop holes would be and Keith drilled them out.
Tank is a good size piece of glass, this should be fun...now to build the stand.
My wife was waivering on where the tank would go after we took out the windows the idea of making that area kind of a breakfast bar was being tossed around but that would put the tank into the wall between the kitchen and living room with most of the tank being in the living room. After much debate the amount of work needed to build a header etc. into that wall and the space it would end up taking up in the living room is simply too much so we are back to the original plan.
about 16 inches of the sides will be taken up with overflows so only 8" of the sides will be seen the rest will need to be covered up with woodwork.

Kurt,
How much extra room will be on the sides of your tank, after you put it in your wall?

After a few days of no progress, picked up wood for the stand then headed over to Reef Creations too pick up the tank (Thanks too everyone there who helped get it into the minivan)
So, built the frame of the stand for the rest of the day and now have the tank up. Plans for tomorrow are to get the plumbing going under the stand and toward the cellar as well as working on finishing the stand/planning the hood.
Some photos of the progress:

Yes, getting the thing level was the worst part...about 1.5-2 hours of my day. I had planed on simply using the old window sill footer however it was not level from inside wall to outside wall so decided too build up and over that. Once I had the top section built I then started to tack legs onto the main portion of the stand with the level (Thank goodness I picked up a compressor and some tools while doing the wifes deck as this was by myself doing all of this)
I do plan on building up the other side with a few 2x6's that are both tacked too the wall and go down too the ground however ended up using more wood than I planed on the main portion of the stand...the outer corners are basically 8x8's after all the build up. Its not going anywhere.

Yes, my wife has told me I am not allowed to break down that system until the new one is up otherwise I would have it down and in the basement.
Hope your willing to wait until the end of the week, by then I should be far enough along to get the 75 tank into the cellar and the sump out from under it. (If I could take the sump out without emptying the main tank we could do that)

Ordered Savco plumbing parts today, had hoped too get them locally but went to two Home Depots and one Lowes looking for the flexible PVC tubing with no luck. I can still install the overflows and work on finishing the stand while waiting for Friday when they arrive.
(Also need to finish one lighting project on the wifes deck and repair the hose line ran too the deck in the mean time)
