Ive been hearing an odd sound from my tank this past evening, and i was curious so i took alook all around tonight and noticed that the bottom trim on my tank is all cracking and bowing out, should i be draining the tank right now, do i need that trim? the tank about a year old and has i belive a 5 year warranty, i am starting to panic the brace on the bottom is all bowed out.but i thought that trim was aesthetic. that bottom trim raises the tank so the bottom doesnt sit on anything. I am using an AGA stand. Any advice would be great!!
