Moving houses, need opinions on floor bracing

Yes water will always find a level and it will drain if it is lower, however as I stated before when installing drainage you have to maintain a minimum of 1 to 2% over the entire distance. If there are any low points there is the potential for debris accumulating and eventually blocking the line. Blocked line = wet floor. A 1" main line and a 3/4" backup line will not move a lot of water if you only have a 1% grade.

What the distance and we can calculate out the minimum elevation change required?

Let's see if this works

If you really want a sump in the garage, a 1' drop and 8' away means you'll need about an 8" drop. More is better. 1/8" per foot is close to code but I prefer to go overkill.
The bottom of your drains need to be, in this case, at least 8" higher than your planned sump. If you can, put your tank on a taller stand.
I was having flow issues with my old setup. In my case, my drain pipes were too small @ 1"
My bulkheads used to be 30" from the floor and now are 40".
I run at least 6' long and use 1-1/2" pipe. Everything has been great for nearly 3 years now.

As for your structural stuff, if you're going to put footings down in the soil, you'll need to dig down at a minimum of 24". 12" is for the footing and another 12" is to clear the frost line. In my opinion it's not worth it. Don't use jacks without a proper concrete footing. It will fail with frost heave if you don't dig it down and pour a proper bed.
Sistering the joists is a good enough plan as you won't get much deflection without them, so I don't see much floor movement once you add material.
Ensure you sister properly. Both sides of each joist need material, and go 100% past your required area.
Use glue and decent screws and leave it alone for a few days to dry.
I'll bet sistering is all you need.

Good luck !!

One thing to note is if you want a perfectly quiet tank a long somewhat horizontal run could be noisy as there will be air with the water running through the pipes. You may have to insulate the pipes to reduce the noise. You could also build a trap at the other end of the run so that you reduce the air in the pipe, however this could result in clogging and reduction in flow

I haven't had any air issues in my drains. Once the air in my lines flushes it's done and dead quiet. And that's running 1-1/2" plumbing with an Eheim 1262.
My return line is 1" and splits into 2 x 3/4" loclines.

My main drain is below the level in the sump(submerged to keep a siphon), and my emerg in above to alert me with splashing noises ... like I'm ever around to hear it

Once my main flushes itself, it runs dead silent. My tank is surprisingly quiet.
I've worked on things to make it quiet with padding and such.
Anyone who's been here buying corals can tell you, and there's been dozens of peeps.

Anyway ...
Don't worry about drainage noise as long as you set up your drains properly.
We can help you work on that later.

Get your tank in place and we'll work on the other stuff later.

Sounds good brother! I was there last night and noticed a poorly repaired cracked joist about 2 from the fish tank, so I'm going to go properly sister that joist tonight and then make my beam with post. The whole room does have bridging in it but I'll feel better with extra bracing

Well got the beefing done yesterday and tank moved today. I'm still a little concerned that when you jump in front of the tank or walk really heavy I see some water movement.
