That's exactly what I found out tonight after doing some research on the net. It's my own fault for trusting too much in other people and not doing my own research and yes, I still have my Solana but right now is full of water and lots of Vinager. I would hate to take the new tank apart because I built an amazing minimalist aquascape :-(
I am running Purigen and ROWAphos and doing daily water changes. Would I be able to keep the tank going if I continued with the water changes and running Purigen and ROWAphos?

I would call GE tomorrow.. There must be a number on the silicone tube. Ask them what's in it, and how long it would take to dissipate.

I was googling and found a post on some chiclid forum.. It mentioned that recently GE changed their formulas so that all of their products now contain mold/mildew inhibitors. I don't know if this is fact or not.. If this is true don't be too fast to blame your bud.. Maybe it used to be reef safe?

Water changes certainly won't hurt!

I think I read the same post. Thanks for suggesting to get in touch with GE. It's a great idea.

I used GE II on my tank and have had no issues at all. I did let it cure longer, but 48 hours should be more than enough time to seal it chemically.

However, this was over a year ago, so if the formula changed, you might be affected by it. Last year your buddy was right, GE II "was" reef safe...

Wow man I'm so sorry to hear about this. Your tank was so flourishing with life

Do like 5% water changes every 2 days, and use alot of carbon.
This is a sad thing to see happen, if you cannot move your corals out of the tank try the advise above.

I just used GE II about a month ago to build my new sump. I read there was issues when it was not left to cure long enough, I left mine for about 5 days until it didn't give off a smell anymore and have had no problems with it. There are two different types, one with mildew inhibitor and one without, I was told to make sure that I used the one without. Are you sure you used the one without the mildew inhibitors?

Really sorry to hear about your losses.....I guess the moral of the story is.... Don't cheap out..... It's amazing to me how many folks look for cheap alternatives for things in this hobby..... Only silicone I've ever used is All Glass aquarium silicone..... Way more expensive than GE or any other brand, but at least I KNOW that it is aquarium safe...... GEs products are not formulated with the aquarium hobby in mind and small changes in formulation can obviously have a big effect..... Again sorry for your issues

Doug, I don't think that's the moral of the story here at all. I'm pretty sure All Glass doesn't make silicone, it's just re-branded, and I wouldn't be surprised if it came out of GE. It's like buying Two Little Fishies seaweed (with the little dotted cut your sushi roll here lines) vs. grocery store nori. One is simply packaged for the hobby at a good profit for the repackager. The same with silicone.
