I currently got a 30 gal
off my brother in-law. Just reasealed it, and made a stand/trim to hold the tank. I left some clearance to put the tank in, about 6mm on each side. 3mm front/back. The tank sits on foam (1/2 inches of foam) , ( incase my house's slant would put stress on the tank). Should I put some silicone along the inside of the trim I made or will it be fine?. I did do a leak test for 32hrs and have let the silicone cure for 2 additional day without water since a successful test.
The bottom trim is missing on the tank, my niece broke it a while back. But he used or for a couple of months with no leaks, found another thread saying it was not safe to remove. Other sources online say its fine. Any suggestions?
