Bubble in primary seal - help!

[mike31154]

What soapy said. I'm no tank builder either, but from the looks of it the 'bubble' is in the layer of silicone that is applied after the glass panes are actually bonded together. If not mistaken, a layer of silicone is added at all seams after the tank is assembled & smoothed out to give that 'finished' look. If that tank isn't leaking right now, I wouldn't sweat it. Clearly the quality control person was having an off day. But this is the internet after all....

It's in the silicone that sandwiches the two panes of glass together. I understood this as the "primary seal". I have no idea how to build a tank, but a buddy of mine does quite a bit of it. He says not to worry but man... I am not loaded and would be so disappointed to have a tank explode and lose a bunch of fish and corals.

That other bubble you see is actually in the water caused by powerhead.. We are looking at the lengthwise skinny bubble in the seam.

That's why my next tank is black silicone. Can't see the bubbles

It's typical, pretty hard to build a tank without some bubbles in the seam. If you only have one you're doing pretty good. That's certainly not going to cause any issues.

Look around at most of the custom tanks around and I'd be amazed if any had a seal as pristine as that. You have only one bubble that's actually pretty amazing. Evey tank I've had no matter how nice they look have had plenty of bubbles. I think I was told once that as the seals cure and tighten up they can actually create those marks.

My 225 was black silicone and I worried even more lol. I could see the joint lighten in colour as I filled the tank and the pull on the seam increased.

That tank looks very well built.

Your build list doesn't have any repeating numbers ... I'm not worried, the best part of this money pit we call a hobby is the build anyway.

carriej, sorry for jacking your thread

If it were me, I'd let the builder know of the bubble and see what they want to do about it.

As others have stated, you are fine. I have never seen a tank without some bubbles in the seal.
