I just recently bought a used 150g saltwater tank off one of our club members and I've slowly been working on it.
This is what I've done with the sump.
When she had it the water went into the sump through 2 pipes that were just siliconed into place. So I cut those off made the holes a little bigger and added (2) 1" bulkheads in their place.
