Godly3vil Posted September 23, 2012 Report Share Posted September 23, 2012 If it were me I would empty the tank and re-silicon it, I have seen worse though on larger tanks. Quote Link to comment Share on other sites More sharing options...

GrahamC Posted September 23, 2012 Report Share Posted September 23, 2012 Are you sure those air bubbles are new? And did you breach the inner seal to pop one of those bubbles?? Quote Link to comment Share on other sites More sharing options...
Li@m Posted September 23, 2012 Author Report Share Posted September 23, 2012 The tank is 60Lx40Hx40D (cm) I did not breach the seal when I popped one of the bubbles, I popped one that was on the very edge of the silicon. I didn't want 100L of water on my floor. Quote Link to comment Share on other sites More sharing options...
livingart Posted September 23, 2012 Report Share Posted September 23, 2012 i have a 60cm high that has been like that for awhile now if amount or size of bubbles increases then i would redo it a bit like mole mapping Quote Link to comment Share on other sites More sharing options...
GrahamC Posted September 23, 2012 Report Share Posted September 23, 2012 Since they're air pockets, they must have either been introduced at the time of the tank manufacture, or, are coming in now from the outside. In the latter case you would then expect it to be near the air interface but they're not. Ergo, a manufacturing issue and not generally a cause for concern.

Sophia Posted September 23, 2012 Report Share Posted September 23, 2012 the stuff that matters is the bit in the sandwich between the glass though, stuff that is sitting on the tank wall comes off quite easily when it ceases to be new.

Li@m Posted September 23, 2012 Author Report Share Posted September 23, 2012 I have been keeping any eye on it, and it doesn't seem to be getting in between the two panels of glass. Thanks for your replies every one :thup: , I'm in the process of getting a new tank made Quote Link to comment Share on other sites More sharing options...

I agree. The silicone between the join is what you should worry about. I hate seeing silicone like that smeared on the glass. Silicone needs to have size/ depth to it to have any strength. The edges should not be feathered like that and are a weak spot to let water/air under which looks dodgy but until you get air/ water bubble in the glass join i wouldnt worry.

Ira Posted September 23, 2012 Report Share Posted September 23, 2012 silicon doesn't last forever Silicon quickly forms an oxide layer on the surface that protects it from corrosion. So it lasts practically forever, unfortunately that's not what we use for our tanks. Silicon Silicone Quote Link to comment Share on other sites More sharing options...

brett2003 Posted September 23, 2012 Report Share Posted September 23, 2012 I've had a couple of very similar looking air pockets in the seams of one of my tanks for a year or two now, and they've shown no particular signs of getting any bigger (despite the tank being moved once and stripped down twice in that time), so you *might* be lucky!

alanmin4304 Posted September 23, 2012 Report Share Posted September 23, 2012 I suspect they are from when the tank was built. I have never seen bubbles arrive later even on realy old tanks left outside---the fillet may delaminate and start coming away but I don't recall seeing bubbles.
