Acrylic tank question

[Raulyacoub]

Good evening guys! I’m new to this forum
I’m the owner of a nano reef tank and a 75 FOWLR.
I recently bought a 240 clear for life uniaquarium (AIO) tank, used. It was in very dirty/bad conditions, but not leaking at all.

After spending all day today, cleaning it, I noticed some kind of white spots between the bottom and front panel seams.

Is this something I can easily fix with weld on #4?

My plan is to pour some Weldon #4 first inside the tank where the seam is. Then I already bought an Acrylic triangle rod to try ti seal it with weld on as well.

Do you guys think it will be enough? Tank isn’t leaking at all. My only concern is if in the future it starts leaking.

Here are some pics, last one is the problem I’m talking about.

If you can get the Weldon 4 to 'wick' into that flaw, it should work. How big is that damage?

 

[Raulyacoub]

There are like 7 total, very small like 1” or less.

Where the red marks are.

Use weldon 16 not 4. 16 is thicker and works for repairing acrylic. 4 probably wont work

Copy I bought Weldon 16, will arrive next week.

Should I use it in the tank before the rod? Or when putting the rod? Or both times?

To wick into the cracks, I believe you would want a thinner version of Weldon.

So, personally, what I would do is use the 4 to wick into the problem spots. Then, use the 16 to glue the rod in place.

That said, others with more experience working with acrylic might disagree.
