I have a quick question. Did you see many air bubbles in the silicone when you built the tank? The reason I ask, is that I guess I did not do a great job siliconing my cross brace in and there are small air bubbles. I have noticed that since filling the tank, they seem to have gotten a little bigger, which worries me a little. Im sure it will be fine but I guess the water is putting pressure on the brace (as it should) and when the silicone is being pulled, the air bubbles are getting a bit bigger. Just wondering if you saw any of this with your tank? I ask my step father about it because he used to build tanks and he said it should be fine for a cross brace but it would be really bad if it were the actual corners because each bubble makes the silicone significantly weaker. I think Im just worrying too much though
EDIT: Sorry that turned out not to be very quick!
