Lots and lots and lots of people have done it this way without issues. My 180 is going on over a year, and it was in bad shape when I bought it. Unless your 40 has been used as a tether ball, you should be fine just "replacing" the interior siliconeSo are you guys basically telling me this to even worth bothering with? Since I'm not completely dismantling the whole tank?
You and most other people would refer to that as resealing a tank!!! Some people just think if you don't do it their way you are doing it wrong... I just can't believe someone would say that paper thin silicone between the glass is what holds the tank together and the other silicone is just to protect that silicone!! LMAO....I believe the more appropriate term for that would be "rebuild". Anyways, I do believe the OP just want to pt a new application of silicone to the continuous corners of the inside of the tank........which I would refer to as resealing
You have got to be kidding me INTHECOWBOYSWETRUST. If you really had rebuilt 40 or 50 tanks as you say and had actually done some research you would know the physics behind this. Lets tank an example besides an aquarium. You are building a wooden box out of plywood and wood glue. Where would you put the glue at? It sure as heck would not be into the corners, you would put it between the two pieces of wood. Glue in the corners would add nothing to the strength of the box you are building. Same exact situation with aquariums.
As for your comment
Well now you are talking about 2 different things here.... wood and wood glue have nothing to do with a aquarium and silicone!!!! If I wanted to make a wood box I would build a 2x2 or 2x4 frame for it then cover it in plywood, I sure would not try to glue the plywood together!!!
But I'm not even going to sit here and get into this with you because you basically just called me a liar and said I live in my mothers basement!!! My mom died 5 years ago so I don't think I live in her basement... I have owned the home I live in for 10 years now and had 3 others before this one!!! SO ONCE AGAIN YOU ARE WRONG!!!!
And no I won't laugh my butt off at anything because I did not say the way you do it is wrong... Actually that is the best way to do it but in most cases it is overkill and not necessary!!!! He was asking about resealing his tank not making one from scratch!!!
Again make a tank and just put the silicone between the glass and not on the inside and see how that works for you... Prove me wrong since you know everything!!! Or stop giving people bad advice and then trying to put someone down and talking $hit about them because they don't agree with your way of doing things!!!!
