Seems like an obvious answer, but...

If I was going to switch from a 55 gallon tank to a 36 gallon tank, if I managed to transfer the water from the 55 to the new 36, it wouldn't affect the parameters or cycle of tank would it? Tank has been up for a year. Potential space issue in new house so I'm curious about this. Thanks

I dont think there will be any issues. But going smaller will result in parameter swings being more prominent.

A few issues: you cannot move the sandbed without cleaning it, and you can expect a 5 day cycle at minimum. So your fish need to be in qt for that period at least. Outside of that, it should go well. Bear in mind that a 30 will keep corals (with adequate light) and invertebrates and the smallest species of fish, blennies, gobies, the smallest jawfish. If you have a problem in this area, you might work a trade of livestock with your lfs.
