Rare earth magnet pull force

Your question does not have a simple answer. There is no specific magnetic field or force required to 'penetrate' 1.5 inches of acrylic, per se.
If you want two objects, such as two oppositely poled magnets or a magnet and a piece of ferrous metal, to be attracted with a specific amount of force, that would require some math beyond the scope of these forums.
I suggest instead, that you consider buying coated magnets & experiment until you get the desired result. You may also stack them together to increase pull strength. Here is a link for coated magnets (they resist water/corrosion). They also have rare earth magnets which are much stronger, but un-coated. So, you may need to DIY coat those yourself, if required. Good luck!

Thanks for the resource! From what I’ve gathered myself, seems like there is no simple answer, like you said.
That being said, I’ve worked out a partial solution with the tank manufacturer, as well as bought an experiment powerhead (gyre 280 with a listed max thickness of 1.25”). I’m having the manufacturer drill holes just bigger than an mp40 dry side on the back wall, then “patch) with 1/4” acrylic so I can place 2 of my mp40s on the back wall without trouble.
This tank will definitely have some DIY/custom flare (single back wall overflow with 4x drains and 4x returns), and I believe that it will be the best tank I’ve ever had.

I can't wait to see this thing!
Watching this build.
