Can I add silicone over existing

[ReefHog]

I have a new Marineland 75 with black silicone I’m getting ready for a future build. I really like the black but would like it more if it was slightly wider. I am thinking of taping the corners and adding more silicone over the existing silicone so it has a beefier look. would this cause any problems?

I don't see why it would cause any problems. I'd say go for it.

The new silicone won't bond to the old. Just figured I would warn you.

why would anyone want to see MORE silicone? Look beefier ? Why ?

I like the look of the black corners. Cleaner look compared to clear silicone imo. I'm sure I'm not alone or they wouldn't sell so many.

Wasn't sure about that but I think I'll pass as I'd hate for it to start peeling. Thanks for the input.

You have to remove all the silicone off the glass in order to use new silicone

You can always reseal the tank. Just make sure you don’t scrape too deep into the silicone in between the glass

It’s a new tank so I really don't want to mess with it. Glad I asked here though cause it never occurred that it wouldn’t stick to itself.

If it is just for aesthetics I believe you could use black liquid rubber. Tape the glass to make a straight line and paint it on. Should stick to the silicone and the glass.
