90-gallon getting back into the hobby tank...

Awesome. Check you my build thread. It started in October 2022 and I still don't have the tank in place 
Woot woot!

Go to Home Depot. Buy a gallon of Muriatic acid. Put 3-4 inches of water in the tank and add a cup of the acid. Get a bottle brush and dip it in the water and spread it over the glass and then scrub it a bit. Every bit of that white stuff will dissolve.
Pour it down the drain or neutralize it with baking soda or let it sit for 2-3 days and it will dissipate. You can smell when it is gone.
If you get some on you it will burn a bit but just run water over your skin or wear some gloves. Now that I have old thin skin it hurts more. It never even burned when I was younger. Aging sucks big time.
Muriatic acid is dilute hydrochloric acid. It will work much faster since it a strong acid as opposed to vinegar or citric acid.
Strong acids are those that completely dissociate into their ions when dissolved in water, meaning virtually 100% of the acid molecules ionize to produce hydrogen ions (H⁺, typically as hydronium ions, H₃O⁺) and their corresponding anions.
Use new bulkheads. The gaskets get hard and don't seal good on older ones.

Going to HD today to get material for the stand, so I added it to the list, thanks!
Going slow, obviously, but there is so much I have to figure out. The list is pretty long.
Build Stand and Canopy
RO unit
Salt
Bulkheads
Powerheads
Return pump(s)
Light(s)
Sump
Plumbing (return lines, drains, etc.)
Rock
Sand
Starboard or Eggcrate
Heater(s)
Controller
Refractometer or salinity meter
Test kits
Filter Sock(s)
Magfloat(s)
And I have to figure out what to choose on all of those... Yay me!

Well, it is not perfect, but it is at the "exceeds expectations" range of my skills. I talked to a couple of engineers (pictured) and they said I would be fine using the left over 2x6's from the garage, so I only needed to buy five 2x4's. The floor in my office is textured tile (i.e.: not flat) so I am thinking about using 1/2 XPS rigid foam board under the stand to soak up the irregularities. Stand might be a tad bit overbuilt...
100 years from now…the house will be gone but the tank stand will still be there. 
Looks good!

I see plywood on the top and bottom. I would remove it. Is the stand built to fit the size of the tank? The plywood on the bottom will be soft and interfere with shimming the bottom of the stand to level the tank if necessary.
How is the plywood on the top retained. You dont want metal fasteners under the edge of the tank.

Yeah, the 2x6 stand perimeter is the same size as the plastic frame on the tank (36.5"x24.5"). I used counter sunk deck screws on 3/8 plywood. I had all this stuff laying around in the garage. My plan is to use 1/2" rigid XPS foam (the pink stuff) under the tank. The frame is 3/8" so I should not have to worry about the foam touching the bottom glass and the foam should even out any slop in the stand and tank frame. I could just remove the ply and go right onto the 2x6 frame, but I am a little worried it is not even all the way around. I was going to seal the bottom with caulk and paint to catch and spilled water. I planned to put the stand on a piece of the same foam to account for the texture in my floor tile.
I guess I have some more research to do
