Ideas for a new tank

[bucketaquatics]

I've got a 20 long and I'm considering making it a saltwater tank. Definitely not looking at a reef tank, was thinking more a fowlr tank. Was just looking for ideas on:
1. Equipment(,lights, heater, filter, etc.)
2. Livestock.

Any and all input is welcome as are pics of your setups for inspiration.

This probably isn't typical, but I had a macro algae tank a while back in a 20 long. The tank was pretty simple. It had crushed coral substrate, a few pieces of live rock, and a bunch of macro algae. I used a light meant for planted aquariums and a hang on back filter. I didn't use a protein skimmer, because the algae did a pretty good job cleaning the water.

The algae grew well and was quit pretty. It needed a bit of trimming from time to time, but nothing worse than freshwater plants.

I don't remember which types of fishes I kept in this tank, but I suspect pretty much any hardy, nano fish would do well. In a smaller tank, I had a Yellow Watchman Goby paired with a Pistol Shrimp. That was a pretty cool duo.

I'm definitely leaning more towards some type of shrimp. Goby's look awesome as well!
