Resealing tank


Recommended Posts

So my brand new marineland 75g has the worse silicone job I have ever seen 1 of the seams the silicon doesnt even go onto both panes the structural silicone job is fantastic but the seals are garbage. I cant warranty the tank either because Ive drilled it already.

That sucks,I've done 3 exchanges on a aqueon because the same problem and also because it was tempered.  Its alot of work re sealing that size tank. Have to remove it all pretty much and reseal all of it in 1 go or it won't cure together properly.  But it can be done. Biggest ive done is a 65 and below.

Yikes…. Tagging along because I have no clue how that can be fixed without a complete resiliconing.   

I've done them on rimmed tanks. Up to a 65gallon and few 55 gallons. I removed all the interior silicone with new razor blades,left the exterior seal on rims. Alot of cleaning and wipe down with rubbing alcohol. Then resealed. Tried tools for silicone, but finger lays it the best. Lay the beads of silicone then mist a little water over it,then run finger over it to give its finish. Let dry and clean up with razor after curing. Its a messy long job.

From my understanding i just need to scrape the interior silicone and leave the structural silcione alone clean it up good with acetone. I heard pencil erasers work good as well.

Well this is going to be easy! After spending an hour of working up the courage to take a razor blade to my tank ive completely cleared two seals in about ten minutes time! Hopefully the other 6 go as easily

Yeah i just went through with a flashlight and got all the hazyness out vaccumed then acetone wipe down vaccumed again and just finished resealing it. Ive got one seam that started to skin up so the surface looks kinda bad but i went with 8mm beads because to stay with the same thickness as the glass. But im done now and will let everyone know if it holds water next week lol

Yep I used ASI black silicone its goes off fast though you get about 10 mins before it skins.it looks 10000% better with tooling imo than the finger spread method. Another thing is that the vinegar smell is not nearly as bad as most people have said it is either. And its not crazy expensive.
