    I am so sorry this has happened to you! I have no time today to help, but I hope you can get it fixed. If you sealed the tank, even though it has gone wrong, you can do it again and get it right.

    Basics:
    Strip the nasty silicone with a razor knife and clean it up with acetone

    Silicone (I use GE I, but any pure silicone with no mold inhibitors works, some even say aquarium safe)
    Tape the seams
    After you lay down the bead, make sure you spread it into the corners with a gloved finger so the seal is firm
    Let it cure for 48 hours!

    What size tank is it? If it's a smaller tank, say under 40g's, it might be worth just buying another one by the time you find someone to help you reseal it. Resealing a tank doesn't take that much time. Just make sure you use GE Silicone I window and door, clear. It should say 100% rubber silicone.

    Also you have to let the silicone dry for about 24-48 hours depending on the humidity. I let mine dry/cure for over a week to be safe.

    I used the wrong stuff before too. It sucks. Mine was a small tank, only 33 gallons.
    Home Hardware sells the right stuff. It even states on the bottle aquarium safe. I use that now. Less than $3 a tube. Best of luck

    If you resealed the first time successfully, the second time will be the same. Just use proper aquarium safe silicone this time and you will be fine.

    If you want a good how to video check out youtube You might even recognize the young fella in the video.

    Try, try again. The first one I did was my 90g leaked like a SOB first time, works great now. Waiting for a 46g bowfront to cure at the moment.
