HELP! Silicon In New Tank Comes Off

[surgeonfish]

Hi All

I have been reefing for more than 15 years and have several tanks before both customs and off the shelf. Recently customed my latest addition and delivered on Chinese New Year Eve. Other than the weekly cleaning using nano algae cleaner I hardly maintained as I was busy. This morning I found the silicon frays off in the tank. Just inspecting the dry portion also notice about 1mm is not glued to glass. Never seen before in my previous tanks.

Why like that?

Please share your experience. Thanks

Sebastian

you should inform your tankmaker.

What do you think causes this?

Ooooo .. Check out your fish or other lifeform ... They might be the culprit .. Looks like bite marks to me ...

You should check with your tank maker Cheers

Yes, likely to be bite marks. But will the silicone so easily bitten off? I touched the silicone edge with my nails and it seems loose at some parts. Bad silicone?

[Martian]

Likely the quality of the Silicon is questionable...

I got my new tank with these kind of marks .. Initially thought its silicone problem .. But only those silicon that's below water line are affected.. Concluded that they we're bite makes .. From angel or some other fish ..

Repaired the silicone on mine by just putting another layer of silicone over ..

Don't think it's tank maker's problem. Looks like accidental scrapping.

Hi YT

Definitely not workmanship problrm. But I only used nano magnetic cleaner. And less than 10 times. Vannot be scrapping.

Hi Xiggie,

Will the overlay hold? How long ago was that?

Bought the tank bout a month ago.. The original black silicon integrity was not compromised .. So I just figured another layer of silicone would just help .. Should have used black silicone too but can't find any .. So just used the normal ones ... Tank is bout 4weeks old now

Hi, You bought a brand new or pre-loved tank? Sebastian.

bro you should ask your tank maker to come down have a look..or go any shop who sell construction stuff ..they should have waterproof silicone ( quite easy to find )

cheers

bro, you should get it done asap before the silicon give way

Tank should have at least a year and some 5 years so better to call the tank maker over to check.

Btw, same thought as bro YT, it looks like it was scrapped off by scraper as encountered before in my previous 3ft tank.

[xiggie]

Bought the tank preowned .. Bout 1year old tank++

No scraper used. Noticed silicone was soft on edge when touched and it's not totally glued to glass. Have called tank maker. Will decom and let them redo the silicone
