My newly built 300 gallon by my 20 yr experienced tank builder...silicone question

This is a 12mm tank reinforced with 12mm x 5cm entire base strips and has 2x30cm top bridges in 12mm too. The bottom panel has these weird dots and squiggles for 30% of the tanks length ( the reinforcement 12mm strips ontop of that and has no bubbles btw) and have a 10cm section on the left bottom on side panel ....tanks full and been running 2 wks no changes in bubbles / spots etc .......is this silicone job an issue as im hoping on having this tank for ma.y years ! Thx guys

Small bubbles in the silicone are actually pretty common and usually not a sign of weakness. In many cases it can be related to the tensile strength of the silicone being used. Some of the stronger structural silicones are thicker and the gases created during curing have a harder time escaping, which can leave small bubbles behind.


The thickness of the glass and the size of the silicone joint can also play a role. When you have thicker panels or a larger bonding area, it becomes more difficult for those gases to work their way out while the silicone is curing.


Because of that, small bubbles in the seam often show up even in very well-built tanks and don’t necessarily indicate a structural issue.

Thats exactly what it looks like too mate! Gasses that tried to escape....hes very specific with the silicone he uses too! He cant source it in black any more so only uses clear ...as to the brand i dont know as havnt asked but he'll only use this particular silicone on all of his builds ...and yes theres a decent layer of it between the panels too
