i filled up my 55 halfway and leveled it with shims. Then i filled it up to my fill line (I use the trim on the tank as the line) and now it’s about 1/8 of an inch off, maybe 1/6. It’s also the same from front to back. I’m at my wits end trying to get it perfect, I just want to know if it will be safe like this or how else to raise it slightly, since there’s already shims.... here’s the comparison pics- and the level how it is now
