Acrylic seam repair/ assessment

[Johnpeck1]

Hi, new to this forum.
200 gallon built in acrylic aquarium came with my house. I noticed moisture on the sheetrock wall. Can you please look at these pictures and yell me whats going on. 1st 2 pics are the side where its moisture. Theres a square acrylic rod running down seam. Looks like theres green straight through which makes me think thsts where its leaking. Above it is also cloudy as you can see. I cant see where its lesking becsuse the wood beam is in the way. Is there an easy remedy for this? Its hidden behind wood trim. I have nowhere to keep the fish if a full drain is necessary. The area is in the top 1/3 of the tank. Was thinking i could drain and run cannister filter temporarily to repair it, buti have no idea whst to do or whatt Im doing.
The 3rd pic is the other side where i see lines behind the acrylic rod. Is this failure?
Any advice would be appreciated.

my 300 gallon has the same small lines but never seen green algae in between the seams. I am going to inspect my tank when get home tonight. Thx for sharing.

What are you going to see from topside that a direct photo of a terrible looking seam won’t show you?

The white is the acrylic panels separating. The green would be algae growing between the two panels indicating that water has managed to get that far and likely through at this point. The acrylic rod is a repair attempt the previous owner must have tried (unsuccessfully) with the lines being micro fractures from stress even with the repair (think of pressure cracks in ice). You could attempt a repair on this tank once again using Weldon 40 and cleaning the edge with sandpaper. You won’t be able to get that algae out of the seam though. I would personally scrap the tank seeing as a repair was already attempted and failed.

Agreed…you can’t salvage that with a simple patch or glue job. You can take it to a shop and have them cut the panels out, removing all the glued edges. Then have them remake the tank with clean seams/edges

I doubt any shop would do that. The amount of work involved in that isn’t worth it.

crazing happens for several reasons the reason i asked about the topside is to see how it was braced. As something is niggling at me that the bracing is only coming from the sides where the wood is at. OP does not want to empty the tank- hence us having to make sure theres a brace happening on the topside- it looks like it was custom made for that wall. If its urgent to empty it out or risk more time if theres no brace ill recommend it to be emptied out before it gives out ASAP yea the panels are not sealed together smooth its separating and its matter of time before it just break loose on that section

It’s worth a shot if he can find someone to do that as acrylic panels that large are worth plenty
