Acrylic sump tank repair, air bubbles in between sheets, still useable?

[kool-cat]

I just repaired an acrylic sump and there are air bubbles/pockets trapped in between the two acylics. I used a acrylic piece to patch over crack inside. Is the tank still usable and can be filled with water or is it a hazard to do so? I want to make another tank and had that sitting around.
