Importanceof center bracing...

[Pan]

If you remove the center brace the tank will bow, the structural integrity is compromised and something will happen, though not always as quick as you'd think. I had a buddy that used one with the center brace remoed for two years, i told him not to, eventually it cracked and ruined his wifes new floor. I think best bet would be to drain and fix. I have no experience fixing them though so if anyone else knows.
