Follow up on GE silicone II window and door used on my sump

unmc2001 · 05/31/2006, 02:50 PM

Well all my corals are back to normal. I used some GE silicone II to place baffels in my sump and after adding the sump the corals in my tank were not looking so good. My finger leather and toadstool closed for nearly a week and the other corals were not open all the way. Now everything is back to normal. I am not sure what caused the reaction from the corals but I thought it may be from something in the silicone II. Everything is back to normal and doing well.

I recently had my corals do the same thing after redoing the sump using ge silcone 2.. Its been two weeks and things are just starting to open agian. Ive used it before and havent had a problem but this time caused trouble in the tank , and i even let it cure longer than i usaully do.

I think they may have changed it from what i remeber even the label is different gonna see if I have an old tube around tonite.

Btw Menards carrys aquarium silcone now and it was about the same price as the GE. I bought a tube and will try it this weekend.

One of the main ingredients of silicone is isocyanate (same stuff in super glue). It is VERY toxic (bottle has a skull and crossbones on it, for real!). Another ingredient is acetic acid (vinegar). Although not as deadly as the isocyanate, it can cause some issues with your pH. Although the tube may say it is cured in a day, manufactures consider full cure 7-10 days (I used to work as an assistant chemist for a company that manufactured silicones for the automotive industry). I would pay the few extra bucks and get aquarium silicone.

Just use silicone I not the II. It doesnt have that mold crap in it and it works great!
