I am a long time reader and first time poster ... I am interested in purchasing a 200 gallon tank in the future as a upgrade to my 90 reef...and a OPE250 in the near future to replace my ASM..I have a 20 long sump and was wondering if the OPE 250 would fit...I know the foot print is 16x16 but I don't believe that to be the circumference. Is this fit possible?
