New tank arrived, is this acceptable?

[NickHolmes]

New tank arrived yesterday from reputable tank builder. The seam at the base of the floating back panel has these voids/air pockets along the whole 1 metre edge, there are also a couple smaller ones on the sides and front. Will these seams fail long term or should I send it back. 12mm low iron glass. Single base. The upright seams are fine. I think I know the answer but would appreciate an expert opinion

2 of the pics automatically rotated, they’re all on the base. Ignore the sloppy silicone above, that is to secure the black acrylic background to the glass
