DIY Ca Blowout

Tested my DJ88 Calcium Reactor for about 2 weeks, clearing up some microbubbles and air getting in the system. Put a jug of ARM in it this weekend and tested that too, with the Co2 out at the pool.
Put the reactor in the house, on the tank, ran 3 minutes and blew out the whole side of the reactor, top to bottom......all over the carpet.

I didn't hit the side of it, or stress it. Looking at the break, the welds all held. It split the sheet in half, on the seam, going around the welds. All I can think of is stress fractures in the acrylic from sawing??? I'm using a 10" 80 tooth carbide blade and then routed all my corners square afterwards.
I used the HomeDepot .220" stock. This has me worried, I just bought a 72x36 sheet to start my sump.
On the Rx I have now reglued the seam with Weldon #2, let that dry and filleted the corner with some #16. Did the same fillet with the other 3 corners.
Pump was a Mag3, the ball valve was closed off a bit to slow the pump down, effluent was wide open.

How did you feed water to it? any chance of pressure building sa from feeding directly from your return pump?

Nope, I was running a sipon from the tank and out to the sump. All I can think of is that I valved off the return to the reactor pump and thus built up pressure on the exit side. Didn't notice any bowing of the sides at any time.
