In my opinion you will regret it. I will shortly tell you my story.
Wifey got pregnant with twin boys, I decided for the sake of time, my marriage etc. to downsize from 100gal reef to 50gal cube tank reef (24x24x20).
Initially it was all great, easy water changes, every 7 days 5-6gal buckets, 15 minutes done.
But I quickly run out of space for corals, miss like crazy bigger fish, its just not the same.
So in the meantime I bought 16gal cube just for some nice zoas and some lps like small frags of acans or blastos.
That still does not cover my love for bigger fish... so wife proposed maybe its time to bring the 5ft long 100gal tank back. You do not have to tell me twice, bought already rock at Aquapros, started to clean the tank, because it still had water in since last year. I will bring it back, put some dwarf angelfish there, some butterflyfish and maybe one tang or sargassum trigger which I miss like it was my baby (sold it here on RC). I know that tank is not the biggest, but since its 5ft long its better for fowlr than reef anyway.
I know maintenance can be a pain in you know what, WC etc., but to be honest I miss it, I miss the size, miss the overall presence.
Maybe just change to fowlr for some time, you can skip WC here and there, but you still have a big tank. Just my thoughts.
ps-thankfully I did not sell my acrylic tank that I got as a bfday gift from Old Town Aquarium, I wanted to give it up for 600-700usd and nobody wanted it, blessing...
