Bubble in tank silicone seal!! *Pics*

Hi all,

I've got a used aquarium aqua aspire 55l. I was about to set it up and found it has an air bubble one one curved bottom corner where the glass pieces join.

I'm paranoid about setting it up now I don't want to set it up even if it holds incase it lets me down in the future. It's one of those new tanks with minimal silicone bead. The rest is sealed very well as you can see. Is it possible to seal it with a thick bead of silicone allover on top of the existing silicone? Thanks

 

If it's only a 55l (not much water = little stress on seams), I wouldn't really worry about it. That's just my opinion though.

 

Silicone doesn't stick to cured silicone. To do properly you'd have to trim out the old silicone first. But if the seal is as minimal (narrow) as you say, laying a wider bead of new silicone on that section would seal on the glass. And since it's the bottom it wouldn't really be noticeable.

I too would likely just use as is. Even if it starts to leak, it'll be very slow, like seepage, not a blow out.

Thanks for the replies and yes the silicone is narrow so I think I can get full cover with a thick bead if needed. It is only 55l aswell.

Problem is if it developed a leak I don't have another tank to move the fish while I empty and repair this one, just thinking worst case scenario.

 

Not having another tank is a problem even if this one never leaks!

That's true. I have a slightly bigger tank I will set up at a later date after I'm done with some decorating. I think I'll fill it up and see how it sits and take it from there. I don't mind a leak just blow outs scare me lol
