Hey guys I'll add on here, my tank (150 gallon 6 ft long 24" width and 20" height is of 4-5/16ths of an inch as far as water level. Should I reconfigure?
my tank is out front to back by about 1/8" on water level and had no problems. nobody notices it but me and when I do now I just add a bit of water to get it hidden behind the trim again. I wouldn't be worried about it at all.
