Acrylic seam issue

[Sehkmete]

Bought this tank brand-new from advanced acrylics and I noticed that this seam wasn't bonded properly. This is the only seam that looks bad. Is it a risk or should I add some silicone to that joint to add durability.

Poor craftsmanship and QC. But I doubt it’s a structural issue. @Lowell Lemon can answer that question as a high end acrylic tank maker.

Tiny bubbles especially in corners happen some times, as long as they aren’t full thickness through the plexiglas pane, it’s alright. Silicone does not bond well with plastics.

Silicone will only make it ugly and possibly void warranty if there is one, will be completely useless on acrylic. Weigh the pros and cons of having to return it/receive a new one if you ended up going that route. Personally depending on how much you spent I would send an email to them about it 100% to get their opinion atleast. This will also create a paper trail incase they have any clause for you to report issues within x time.

I emailed Advanced Acrylics a week ago and I haven't received a response yet. I wish they were better about responding but it is what it is.

Hi,

That‘s a brand new tank, I am returning that for an exchange regardless.

I have a new acrylic tank coming in a couple weeks...if it looks like that I will be having an argument with them. But I ordered from a different place.

Silicone is for glass you want acrylic sealant , I would add some for peace of mind

It is possible or the solvent ran during assembly. Small bubbles are not desirable but may not affect the seam as far as leaks. Looks like the tank has a black bottom?

 

[Sehkmete]

How thick is the acrylic?

1/2 inch and the bottom is black.

1/2 inch and the bottom is black.

Probably okay. It is a little on the thin side for best results. The bottom looks thiner...more like 3/8". So make sure you put the tank on a stand that supports the entire bottom. I would prefer 3/4" or more for best practices. Just my personal opinion. I built lots of 240's and 180's out of 1/2" so it should be okay. The front panel will bow slightly though. At this point it is your call but the bubbles are more cosmetic from the pictures than structural.
