    hey I was wondering if this silicone I used to reseal my tank can't be used. My tank has been setup since December. I had a cyano issue because of some pukani I believe were leaching phosphates. Took them out and used chemi clean twice and so far so good. I have a couple of fish (pair of clowns, chromis, yellow tang, sail fin and flame angel) that are doing fine but I'm having trouble keeping snails but crabs are fine. I have recently read that silicone 2 causes crashes etc. and would like to know if maybe it's the silicone. I'm trying to identify the problem. Any input is appreciated, thanks!

    Just buy the stuff from your LFS....
    I have heard that the GE is fine but you need to wait until there is NO SMELL before using the tank (Full curing times vary depending in climate)

    the mold free is what would have turned me off from using it.

    Yup, +1. But certainly need to let it gas off at least 1 week, 2 is better. Silicon especially in between two glass panes needs time to fully cure and gas off.

    When I did my tank, all my research pointed me in the direction of GE I and NOT GE II because of the mold free additives.

    I'm not sure about the validity of it, but that's what my I found while researching.

    Mold free = bad.
    Unless it specifically says "aquarium safe" I would not use it. You are not saving money if you kill everything in your tank.

    I resealed in December , if I could back I would obviously get it from my LFS. I'm just wondering if it's safe or not lol. Research points to that it isn't, I'm getting mixed feedback and my fish are fine. So idk if I should be waiting for a crash or not

    I just re sealed a 90 that I just got with the black silicone 1. I still have to get the tank glass cleaned up and a sump and such so im sure I will be way over two weeks before I have water in it. Nice looking reef hbetanzo!
