Losing Corals fast...question about GE Silicone II

[Carrera75]

Another reefer and I built a back chamber for my new cube tank and we used GE Silicone II. I set up the tank and almost immediately I started losing corals and I blame the GE Silicone II. Is this product reef safe?

Another reefer shared this link not long ago and it makes me think that the other reefer that helped me out build the back chamber used the wrong Silicone.

I recently shut down my 34 gallon Solana and set up a cube tank. This transfer was very well planned and I made sure that all corals, fish and liverock were placed in Rubbermaid containers immediately. Each container had a powerhead or two to keep the water moving and a heater to make sure that the temperature remained stable. All corals were open and happy during this time but all this changed as soon as they went into the new tank.

Tank is currently not doing well and I am losing corals fast and I am afraid that the GE Silicone II is the responsible for all the loses. There is no other explanation for what's going on in my tank. The liverock has been in my systems for the last 7 years and I used new sand. I get it that a small cycle might happen but not this. Whatever this is, it's killing my corals. So far I have lost an Aussie Gold Torch, Neon Green and Blue Wall Hammer, Orange Frogspawn, Galaxia and it seems that the Octopus Frogsoawn is on its way out too. All 9 Rock Flower Anemones spawned last night and the rest of the corals are not looking good.

I started doing water changes as soon as I realized that there was something wrong with the tank and finally did some water testing last night. Phosphates, Nitrites and Nitrates were at 0.0 but Ammonia was at 0.25 ppm. I quickly did another water change, waited a bit and tested again. The w/c seemed to bring down the Ammonia to 0.0. I also started running Purigen and ROWAphos hoping that this will eliminate whatever it's that's bothering the corals.

What should I do now? Should I take everything out of the tank to remove the Silicone?
