Salt on silicone seam

[divcesar]

I bought a second hand Red Sea tank and recently I noticed some whitish stuff on the silicone seams. I never filled the tank, I think the white stuff is some residual salt from previous use. My questions: will this be noticeable when I fill the tank? Any way to remove it? Do you think there is a risk the tank will leak because of this?

There is a risk for any Red Sea tank to leak as it's a known issue with these tanks. Your seams look more like scraper damage than a seam about to split to me, but worth noting it looks like its on the front edge of the tank which is the exact problem area for Red Sea tanks. If the damage extends below the start of the bottom panel, then it may affect structural integrity. If it's just the extra silicone above the bottom edge of glass, then it's just cosmetic, for now.

There are several prominent threads about this issue. Here is one of them:

If you want you can link this thread in the seam break thread I posted above and you will probably get some more opinions quickly.

It would help if you could clean the outside of the glass along the seem and try to get some clearer images. I tend to agree with @Cell; probably some scraper damage.

I wouldn't put anything in the tank... if it leaks, you are risking everything - expensive corals, fish, your floor, etc. Not worth it.

Second hand redsea tank with possible seam damage put it in the landfill before it ends up all over your floor

The salt is only on the top portion of the silicone, it doesn’t reach the other glass.

Wouldn’t adding more silicone on top of existing one help mitigate the problem?

New silicon does not stick properly to old silicon. Must remove all old to add the new if you want it to work long term

This. Either reseal the tank properly or trash it.

After doing some research my plan for now is:

1. Remove interior silicone and reseal again. Maybe only the bottom, but perhaps everything.
2. Add vertical support beams to the stand. I was thinking 3x3 in all corners.
3. Add an euro bracing to the tank itself. Maybe also on the bottom part.

What do you guys think? If it works then I’ll be happy to do all this.
