Is this 40g tank seam failing?
Is this tank seam failing? I can see obvious bubbles in the seam.
40G breeder Tank. Has a rim. Tank is approx 4 years old.
This is the view from the front. The side glass is directly mated behind this seam (i.e. this is the silicone holding glass panes together). The darker black silicone is the water sealant. I would prefer not to to have 40g of water on the floor sooo...
