Ok, no one ever told me that Silicone is toxic to fish. Now I have just learned this. Even the LFS that drilled my holes and sold me the bulkheads didnt say anything about using nontoxic silicone. I now have 4 bulkheads in my tank all siliconed in. The tank is full of water and I was planning to add sand and live rock this week. Does all the water have to come out and the bulkheads removed? This could be a nightmare.
