To Steve's credit, he is very responsive to emails. However, I had many concerns with the silicone on my tank and he would either contradict himself constantly to feed me answers that he thought I wanted to hear or flat out dodge specific questions I had regarding silicone, safety factors, and the tank being out square and out of plane. After 10 or so emails asking him for a new tank I just gave up.
The attached photo shows one of the bubbles in the seams, which spans almost the entire span of the structural seam. Otherwise, approx 75% of my tank does not have silicon 100% in the seams as other have recently posted about. I posted about these issues myself over a year ago in this thread if you want to see photos of what I'm talking about just look back in this thread. I'm not going to trash them or start quoting Steve in any of his messages to me, but I was not happy with the tank I received or the responses I got from Steve, as it seemed that he just wanted to say anything to avoid shipping another tank to me.
With all this said, my tank is still full of water over a year later with no leaks and no signs of the seam deficiencies expanding or growing. However, I manage risk and safety for a living, so I'm a little extra cautious of these issues than most. I do worry about water on the floor each time I come in the house or wake up in the morning, and at this point I consider this tank a temporary solution until I save up for a better one.
