resealing your tank
Can I use the GE silicone at home depot? Whats the difference between I and II? Or is there anything else you recommend?

Hey ,
The brand of silicone you choose matters little , as long as it is a non-toxic just make sure it is before you purchase it . I build aquariums and do repair as well an have used a variety of diffrent silicon as a result of specials / deals and diffrent stores brands . Never had any trouble as long as it was a non toxic formula ;-) I'll give ya a go by that may help .
1. 100% silicon non-toxic
2.silicon carbide sand paper
3. ductape
If the glass ( a side has to be replaced ) the carbide paper is to sand the glass edges .
The ductape will hold the glass together and allow the silicon time to cure .
Remember to run a bead of silicon down the edges that aill meet ( both ) after placeing together run a seperate bead of silicone up the inside seam . ( this will ensure that it wont leak ) ;-)
After you've completed the glass placement and silicone leave the aquarium to cure for atleast 24 hrs 48 is better .
After silicone has cured for the apropriate time fill the aquarium with water and allow it to stand for 24 hrs to see if you missed a spot with the silicon .
Dump test water clean well allow to dry and assumeing no leaks your tank is ready . :-D
Hope this helps
God bless

I or II is fine, you want to stay away from the Mildew inhibitor silicones.

So the ones that are waterproof. Mildew repellent(or resistant) should work fine. I got the blue GE II 100% silicone. I didnt see if it said non-toxic. But i havent opened it. Im sure theyll accept exchanges if nessacry.

Okay i didnt read any non-toxic on the bottle. But i read a "do not use below water line or in aquariums." Ill run in and check the red bottle.

The only differences i see are kitchen and window or mold protection and no mold protection.

Hey agin ,
I'd say the kitchen & mold protection might be your best bet . But I cant say this enough '' It must be non-toxic '' or bad things will happen .
Is the problem a leak on top ? a crack in the side ? a bad seam ? What exactly is leakin ?

FishyFishy89 01-01-2013 02:50 PM

Nothng is leaking. There is little to no silicone on the sides. I grabbed the red bottle. Kitchen and bath. Says it is permenately waterproof and doesnt say anything about mold or mildew protection.

No. You do not want anything with mold or mildew inhibitor in it. They will not work. Use GE I or II. Stay away from the others. No bathroom silicone.
