IM tank seam damage, what to do?

[JojosReef]

IM Nuvo Fusion 2 40L (40 gal long)

Broke down the tank and did a tank transfer. I just noticed this hole in the seam that I thought was dried salt:

On closer inspection, I could see that it was NOT salt at all and goes all the way through the silicone:

It looks like something stabbed it while I was breaking down the tank. It does not appear to be in the area that connects glass to glass. It looks like it went through the part that is smeared over the corners (silicone "guard"?)... This part:

Fortunately, I caught this before having someone over to buy it. Of course, I cancelled.

Now I am wondering what I need to do with the tank.

How bad is this damage?

What can be done about it?

What needs to be done to get it in shape for resell? I need to move it out of my office at some point.


Here are some other spots that caught my attention:

Maybe a nick from the glass scraper. Not all that worried about this one.

Same here.


Then lastly in the top corner, looks like my razor might have caught the edge:

Sorry for the out of focus shot.

Hope someone can give some guidance as to what to do next. Thanks! @tangerinespeedo any ideas?

Looks like you just took a chunk out of the corner bead of silicone and not the joint between the panels of glass. Personally I wouldn't be too worried about it. Flush it out with water and clean with Qtips. Clean again with rubbing alcohol and qtips and be sure to get any debris out. Mask the glass above and below the corner bead. Next get a good quality black silicone and put some in a 10ml or similar syringe with applicator tip. Push the syringe to prime the tip and wipe away any excess. Now place the tip into the gap and slowly fill from the inside making sure the silicone fills and pushes out any air gaps at the same time slowly pull the tip out. Use your finger to wipe the excess using just enough pressure to match the bead around it. Pull the masking tape and done! Wouldn't worry about the other chips in the silicone.

doesnt seem structural, looks like cut off the beads on the armored seams

2nd pic looks like something ate through the silicone. I recall reading about some worm eating silicone on R2R awhile back

Thanks, getting similar advice on R2R. I have black silicone I used for my sump baffle. Or does it have to be a brand new tube?

I think you have no choice but to give it to me... I trade you for two Great owls...

Just as long as it's not too old it should be fine.

Two years this month.

Silicone has a shelf life. If you're unsure put a small dab on the bottom of the tank or somewhere inconspicuous where you can easily scrape it off with a razor blade. Make sure it cure nice a strong and bonds to the glass before using it.

Oh, thought you meant the tank! Right, this tube of silicone wa bought in Dec or Jan, I think, so going on 5 to 6 months.

I think that is just the armored seam. You should be fine structurally. Adding more will not adhere to the older silicone, but it should be fine to add more since it is just preventing something to hit the actual seam.

I've done tests in the past and had new silicone bond great to really really old silicone. I could pull it and it would stretch as if the two were welded as one. There are obviously many different formulations of rtv so maybe I got lucky with the two. In your application it's not critical.

 

[Jimbo327]

I think they will still stick together, but I don't think they will bond as it were applied at same time. It will have lower strength. But in this application, it wouldn't matter because it is not holding the glass together.

The silicone break did not go through where it seals the glass panels so I would just leave it alone. Like others said, no structural damage. Sometimes trying to fix something can cause more damage especially for those who think they're handy but are not! lol.

How about those that do not think they are handy and are also not?
