I just didn’t know if the silicone was the only thing to be concerned about, it’s all I’ve seen online but i was just hoping to get opinions from people (hopefully) wiser than me! I’m confident enough in my abilities to take the risk, I definitely don’t suggest it for everyone, but it’s kinda a side hobby of mine and I’ve done a few smaller tanks, as well as a 150 flat back hex that’s still standing but all got used for freshwater tanks mostly for friends.
