If you need a pump and a huge sump moved from a house with a basement setup
big iwaki 100 japanese motor and a 150 sump for $200 OBO
it will pump to the 3rd floor if necessary lol
the extra water and rock it wont hurt your system, unless shocked by uncured rock or temp,,,if thats a problem run it by itself in the basement till rock cures then put it online with your display tank
