3M 5200 will stick to almost anything. I think you may be overthinking it with the tape/foam idea. If you mount the glass to the inside, the water pressure will hold the glass tight to the pond liner. The real problem is that the pond liner is floppy, so when there's no water in the tank, the glass, even if firmly glued to the liner, will fall out of place. I've seen a number of builds where acrylic is used, with bolts through it holding it in place, or where glass is used, a frame is constructed inside the tank to support the glass. The silicone then only really has to be a gasket. Ideally it bonds firmly to both surfaces, but even if it won't, it works like an O-ring seal around the front. Adding tape around the glass doesn't sound like it would contribute to the integrity of the seal.
Plywood tank... pond liner?

Ok, that makes sense... thanks. I'm already getting the glass, it's a done deal... and a pretty decent deal at that...
However, I think I'd like to run a sump filter underneath it, I was thinking of drilling through the bottom of the tank to run the PVC pipes and use bulk heads... perhaps use the 3M 5200 to seal the bulkheads...?
I wonder how available that 3M 5200 is, I wonder if I can get it at Lowes or Home Depot?
thanks again...
I just finished building my first large tank using pond liner (will post a thread soon). I wouldn't recommend drilling through the liner, I tryed a hole saw at first and it just gripped the liner and wanted to tear it, instead use a knife to cut out the hole for your overflow.
That was great tank on the link glass glue in the liner, that was what I'm thinking before. I has see some link plywood build window glass but it a lot of work on fiber and epoxy, liner really simple and hopefully it doing great on the long run. I did 1 outdoor pond and now I'm thinking build 10'x4'x4' with glass window for indoor. Please keep update your good work, don't forget pic

.cv, i used some liner that was left over from a manmade 3 acre lake near where i live. it's more plasticy than rubbery and looks like woven nylon baling twine that has been heat flatened then coated with a black pond armor like stuff. its really durable and a guy that helped do it said it was fairly cheap but he didn't know where it came from, if i find out i'll let you know if youre interested.
when i get home i'll tryto remember to post some pics of the sump i ddi with the stuff and some of the material itself.

What do you seal the pond liner seams with? I am interested in making a tank using pond liner, but do not know what to seal the pond liner to pond liner seams?
Thanks,

Im most cases you put in once giant peice, form it to your tank, fill up and cut the rest off. Thats what I did.
I've seen seamed liners, but they were built to spec, seamed at the factory. They looked hella durable, like they'd almost hold water without a tank around them.
