I got a 90 gal tank for free. People were moving. It was a saltwater tank with a sump and iwaki md70rlt. It had been in storage and was rusted. I took it apart and the internals are good. Sand and paint and it's good. But I destroyed the long screws that hold the motor together. Need to replace them but can't find a match anywhere. Anyone know where I can find these? Could use a new fan too.
