Thinking of setting up my first salt tank

[Ephraim]

I'd prefer not to drill, I don't mind doing a little extra work for maintenance. I enjoy messing around in my tanks, that's half the fun.

I don't plan on keeping any fish in here so that should reduce my filtering requirements, correct? Basically all I want to have is snails and hermits to keep the tank clean and have a few type of soft corals growing on the rocks, more of a "still life" that's why I like planted tanks.
