Bubbles developing in 5 year old tank. When to panic?

[smartwater101]

I've had this tank for 5 years and the bubbles are mainly on the top panel. It goes along the entire top panel (all four sides) at equal distances apart from each other. I also have this around the bottom panel but the bubbles are not anywhere close to being as deep as the top...

I also have a few on the corners but only one or two on each side...

Is there a way to fix this? Is there any need to even worry about it? I was thinking of getting some square rod to weld to the corners, either inside or out... though I'd need to drain the tank from what I remember reading (solvent + full tank = water on floor)

Anyway, what are your thoughts?

Wondering if these are the original welding joints when the tank was being put together during the initial build process. I'm no acrylic expert but that is what it appears to be.

I have weldon 16 and several 10", .6" square rods. Maybe I'll drain a bit of water and at least reinforce the top back and top sides...

Can this tank be trusted for another 5 years?

I'd say its iffy. It may spring a leak at anytime. Do you notice any bowing of the panels?

The top seems to bow slightly upwards. Everything else looks fine

Most likely due to the condensation and heat from the lights.

Talked to an owner of a LFS and he has tanks that have looked like this for 40 years and never had a problem. I'm still tempted to weld in the square rod though...

Either way best of luck!
