Hey all! I am replacing my ancient 29 gallon tank with a 72 gallon bow front I scored for cheap. I had to reseal it since it had been dry (and still salty...) for years, so please ignore the heavy-handed silicone job, it was my first attempt ever. It's not pretty but it worked. Let it cure for a week and yes, I tested it outside. Woohoo, no leaks! Then I installed a prismatic window film and some color-changing LED lights for the backdrop. Lyric the nosy cat for scale.
